People with very mild Red-Green colorblindness may not know unless they are specifically tested. Symptoms of the disease generally are recognized early in childhood. When a parent starts to teach a child with colorblindness to identify colors, it is very hard for that parent to ignore the fact that the child cannot correctly identify colors. When a child becomes school aged and must complete exercises in class about color identification, it is very easy to identify that the child has color identification problems. The most common symptom of red-green colorblindness is the inability to distinguish between certain shades of red and green. A red crayon may not been seen in a bucket of green crayons while an orange one may. |
