Which is better a dichromat or a trichromats?

Furthermore, dichromats have a significantly higher threshold than trichromats for colored stimuli flickering at low (1 Hz) frequencies. At higher (10 or 16 Hz) frequencies, dichromats perform as well as or better than trichromats.

How many different colors can a dichromat see?

Exponentiation suggests that a dichromat (such as a human with red-green color blindness) would be able to distinguish about 10,000 different colours, but no such calculation has been verified by psychophysical testing.

How are chromates and dichromates used in everyday life?

The lead-containing pigment chrome yellow was used for a very long time before environmental regulations discouraged its use. When used as oxidizing agents or titrants in a redox chemical reaction, chromates and dichromates convert into trivalent chromium, Cr 3+, salts of which typically have a distinctively different blue-green color.

What’s the difference between zinc plate, zinc chromate and dichromate?
