There are different types of colour blindness and in extremely rare cases people are unable to see any colour at all, but most colour blind people are unable to fully 'see' red, green or blue light.
Can colorblind see better in the dark
Color vision deficient people have a tendency to better night vision and, in some situations, they can perceive variations in luminosity that color-sighted people could not.
Can colorblind people see red on black
Why Red/Black Can Be Bad. Some color blind users are lacking the capability to detect the lower color wave frequencies associated with red. For these users, red color waves read as "no signal", or "black". These users confuse red and black, so this contrast should be avoided whenever possible.
Is blue and grey color blind friendly

Is blue Colour blind friendly
Use a colour-blind-friendly palette when appropriate

What color is easiest to see
Bright colors are generally the easiest to see because of their ability to reflect light. Solid, bright colors, such as red, orange, and yellow are usually more visible than pastels.
What makes color blindness worse
The most common kinds of color blindness are genetic, meaning they're passed down from parents. Color blindness can also happen because of damage to your eye or your brain. And color vision may get worse as you get older — often because of cataracts (cloudy areas in the lens of the eye).
What color blind can’t see red
People with protanopia are unable to perceive any 'red' light, those with deuteranopia are unable to perceive 'green' light and those with tritanopia are unable to perceive 'blue' light. People with both red and green deficiencies live in a world of murky greens where blues and yellows stand out.
What color blind is red weakness
Protanomaly
Protanomaly is referred to as “red-weakness”, an apt description of this form of color deficiency. Any redness seen in a color by a normal observer is seen more weakly by the protanomalous viewer, both in terms of its “coloring power” (saturation, or depth of color) and its brightness.

Tritanomaly makes it hard to tell the difference between blue and green, and between yellow and red. Tritanopia makes you unable to tell the difference between blue and green, purple and red, and yellow and pink.
