Could he be color blind?

I'm not saying that your child is color blind but those are the first things my child learned after learning how to talk. She is able to distinguish the basic colors at an early age of two. Try associating colors with different objects, first like the color red associate it with an apple, so that he may be familiarized with each color and then try to put that color in other objects and test him if he still recognize the color. Or maybe he is having trouble memorizing the colors' names. Be patient, children matured at different age, for instance I observed that females talk early than males. You could wait too for him to start preschool. Some teachers are excellent in these approaches and maybe they could handle it more than we parents can.

Sounds like he might be. Have yuo checked out any of the patten tests on the intenet, they're everywhere. Here's a description from colorvisiontesting.com about the basic types. You can get loads more info there as well as online pattern tests. "The human eye sees by light stimulating the retina (a neuro-membrane lining the inside back of the eye). The retina is made up of what are called Rods and Cones. The rods, located in the peripheral retina, give us our night vision, but can not distinguish color. Cones, located in the center of the retina (called the macula), are not much good at night but do let us perceive color during daylight conditions. The cones, each contain a light sensitive pigment which is sensitive over a range of wavelengths (each visible color is a different wavelength from approximately 400 to 700 nm). Genes contain the coding instructions for these pigments, and if the coding instructions are wrong, then the wrong pigments will be produced, and the cones will be sensitive to different wavelengths of light (resulting in a color deficiency). The colors that we see are completely dependent on the sensitivity ranges of those pigments. Many people think anyone labeled as "colorblind" only sees black and white - like watching a black and white movie or television. This is a big misconception and not true. It is extremely rare to be totally color blind (monochromasy - complete absence of any color sensation). There are many different types and degrees of colorblindness - more correctly called color deficiencies. People with normal cones and light sensitive pigment (trichromasy) are able to see all the different colors and subtle mixtures of them byusing cones sensitive to one of three wavelength of light - red, green, and blue. A mild color deficiency is present when one or more of the three cones light sensitive pigments are not quite right and their peak sensitivity is shifted (anomalous trichromasy - includes protanomaly and deuteranomaly). A more severe color deficiency is present when one or more of the cones light sensitive pigments is really wrong (dichromasy - includes protanopia and deuteranopia). 5% to 8% (depending on the study you quote) of the men and 0.5% of the women of the world are born colorblind. That's as high as one out of twelve men and one out of two hundred women. I am going to limit this discussion to protans (red weak) and deutans (green weak) because they make up 99% of this group."

why don't u consultant a eye specialist. he will have a better idea.why to take chance. but more chances r due to being un mature he is unable to determine colours.with the growing age he will be soon start getting this thing.
