Working with colors in early childhood is more involved than just pointing at a crayon
The question comes up constantly in forum threads and teacher WhatsApp groups. People want a single code they can drop into their planning documents. There isn't one. The BNCC distributes color work across multiple fields of experience and several codes depending on the age group you're actually working with. I've spent years watching educators struggle with this exact confusion, usually right before the annual inspection visit. Here's how it actually breaks down.
código da bncc para trabalhar cores na educação infantil: what the document actually says
Color appears primarily in the field called Espaços, tempos, quantidades, relações e transformações. Within that field, the observation objectives for children aged 2 to 3 years include EI02ET01, which asks children to describe attributes of objects such as color, size, and weight. This is your baseline code if you're working with Creche-level students. For the same age range, EI03ET01 covers identifying and naming visually perceptible qualities of objects and images. EI03ET04 moves toward using everyday language to express localizations and orientations. EI03ET05 introduces relative terms like big and small, near and far. None of these are exclusively about color. They're about perception broadly. That's why teachers who hunt for a single code end up frustrated.
If you're working with children aged 4 to 5 years, the landscape shifts significantly. EI04ET01 involves ordering objects based on observed attributes like color, size, and shape. EI04ET02 covers comparing quantities using counting and other strategies. EI04ET04 introduces informal measurement concepts. EI05ET01 and EI05ET03 deal with recording and communicating observations using various representation means. Color work for this age group lives inside documentation and comparison tasks rather than simple identification exercises.
What I actually do when a teacher asks me for a concrete plan
I stop looking for the code and start looking at the activity. The code follows the activity. I had a teacher last year who brought me a color lesson she'd designed and wanted me to assign the right BNCC code. She'd planned a sorting activity where children organized colored buttons by shade. It was a solid activity. The codes that matched were EI04ET01 and EI04CG05. She'd written the lesson as if it were purely aesthetic. I showed her that the coding shifted entirely based on whether the children were just recognizing colors or actually comparing and ordering them by attribute. The paperwork changed because the cognitive demand changed. My standard approach for any age group goes like this. You identify the observation objective that matches the complexity of what the children are actually doing. Then you cross-reference the physical development codes because color work in early childhood rarely happens without manipulation. EI03CG03 and EI03CG05 cover body awareness and intentional hand use. A child holding a colored block and placing it in a container is doing physical development work simultaneously with perceptual work. That's not optional. The BNCC expects this overlap.
A specific edge case that catches everyone off guard
Here's something I learned the hard way. When you document color work for inspection purposes, you run into a problem with children who have color vision differences. I worked with a classroom where roughly one in twelve boys in the Creche group had red-green color perception variation. The teacher had built an entire unit around sorting red and green materials. During observation, two children kept placing the red pieces with the green group. The documentation looked like non-compliance with EI02ET01. It wasn't non-compliance. It was an undiagnosed perceptual difference. My workaround was practical and took about ten minutes to implement. I switched the sorting criteria from red versus green to dark versus light. Same activity structure. Same developmental objectives. The same code EI02ET01 applied because the child was still describing and identifying visual attributes. The documentation didn't change either. What changed was that every child could participate accurately. This is worth noting because inspection reviewers rarely ask about color vision screening, but the activity itself should account for it. A good teacher plans for the edge case before it becomes a problem during documentation review.
Common pitfalls that beginners keep repeating
The first mistake is treating color as an isolated subject. You'll see lesson plans that list "color of the day" activities without connecting them to any observation objective. The BNCC doesn't reward this format. Each activity needs a clear link to an EI code that describes what the child is actually doing cognitively. Naming a color isn't the same as describing an attribute in context. The difference matters for documentation. The second mistake involves age placement. I regularly see teachers assign EI04 codes to Creche children or EI02 codes to Preschool children. The age bands exist for a reason. EI02 covers birth to 3 years. EI03 covers 4 years. If your planning document uses the wrong band, the entire observation objective becomes misaligned. Reviewers catch this quickly. The fix is straightforward. Check the child's actual age against the code designation, not the program label. A 4-year-old in a Creche program still falls under EI03 codes. Program labels don't override age bands.

Another issue surfaces with documentation quality. Teachers often record that children "learned colors" without showing evidence of attribute description, comparison, or ordering. The code EI04ET01 requires observable evidence of ordering behavior. Simply stating that a child named three colors won't satisfy the documentation requirement. You need photos, annotated records, or samples showing the child actively comparing and arranging by color attribute.
Practical activity framework that actually maps to the codes
I give teachers a template that works across age groups. Start with a sensory bin containing objects of varying colors, sizes, and textures. For Creche children aged 2 to 3, the task is simple exploration and verbal labeling. You observe whether the child points to or names a color attribute. This maps directly to EI02ET01 and EI03ET01. You document the child's verbal output and the action taken. No ordering required at this stage. For 4-year-olds, you add a sorting tray with compartments. The child organizes the objects by color first, then by size, then by both attributes together. This creates observable evidence for EI04ET01. You record the sequence and note whether the child self-corrects when an item doesn't fit. The self-correction detail is important. It shows conceptual understanding beyond rote matching.
For 5-year-olds, you introduce recording. Children draw or photograph their sorted arrangements and label them using color terms alongside size and shape descriptors. This satisfies EI05ET01 and EI05ET03. The documentation requirement here is stronger because the child is producing a record that can be reviewed later. I always tell teachers to save the actual drawings or photos, not just the caption. The visual artifact is the evidence.
Where this approach breaks down and what to do instead
The main bottleneck is time. Proper documentation for each child across multiple attributes takes approximately 8 to 12 minutes per child when done correctly. In a classroom of 20 children, that's 2.5 to 4 hours of focused observation time spread across a week. Many teachers don't have that window. The alternative is to use group documentation with individual annotations. You photograph a child's sorting activity, then add written notes about their specific behavior. This cuts the time to roughly 3 to 5 minutes per child. The documentation still satisfies the code requirements because the written notes provide the individual evidence that reviewers look for. Another limitation involves classrooms with limited materials. Color work requires a reasonably diverse set of objects. If you only have primary color blocks, the activity scope shrinks considerably. Children can still meet the observation objectives, but the depth of comparison available to them is restricted. My recommendation in this case is to use natural materials. Leaves, stones, and fabric scraps from home bring in subtle color variation without additional cost. A pile of dried leaves alone provides more chromatic variety than most classroom color sets.
Where to find the full text of the codes
The official BNCC document is available through the Ministério da Educação portal. Search for BNCC educação infantil pdf on the official site. The observation objectives are listed in the annexes organized by age band. Each code has a full description. Read the complete description for each code you plan to use. The one-line summaries in planning templates often omit key verbs that determine whether your activity actually matches the objective. I also keep a personal reference sheet organized by code type. Observation objectives, physical development objectives, and language objectives each get their own column. When I'm writing a lesson plan, I scan the column that matches the primary cognitive demand of the activity. Color sorting goes to observation. Color mixing and pouring goes to physical development. Naming and discussing color in context goes to language. This method keeps the planning accurate without requiring me to reread the full document each time.
The short version that most people skip
There is no single código da bncc para trabalhar cores na educação infantil. The relevant codes depend on your children's age, the complexity of the color task, and what cognitive demand the activity places on them. EI02ET01 and EI03ET01 cover basic color identification for younger children. EI04ET01 covers comparison and ordering for 4-year-olds. EI05ET01 and EI05ET03 cover documentation and communication for 5-year-olds. Physical development codes like EI03CG03 and EI03CG05 apply whenever children manipulate colored materials. Language objectives apply when children discuss color in context. The activity determines the code, not the other way around. Plan the activity first. Assign the code after you know what the children are actually doing.
