The process of acquiring the concept of color begins around the age of two and ends around the age of 3.5. As part of the developmental stages, the process of acquiring the concept of color is also gradual. If it seems to you that your child is having a little difficulty and you want to give them the concept of color, it is recommended to teach each color separately. It is possible, for example, to declare a "red week". Dedicate that same week to acquire the red color, emphasize red objects in the child's surrounding ("Here's a red truck", "This apple is red" etc.). In addition, one day you can wear red clothes and another day eat a whole meal of red foods, craft with red fingers/red colors, etc. Use your imagination." Zoe's Book of Colors" is another experiential way of getting to know the color.
