blindness , which accounts for 98 % of all cases of color blindness ,” said Kent Streeb , Vice President , Communications & Partnerships , EnChroma . “ About 1 % of people are blue-yellow color blind . A smaller percent has achromatopsia and they see in shades of gray and black .”
Color blindness is a bit of a misnomer because the color blind do see color . Individuals with this condition struggle to distinguish between red and green hues , often perceiving them as shades of gray , brown or yellowish .
