Answer 1

The color of a diamond may be affected by chemical impurities and/or structural defects in the crystal lattice.
Diamonds occur in a restricted variety of colors — steel gray, white, blue, yellow, orange, red, green, pink to purple, brown, and black. Colored diamonds contain interstitial impurities or structural defects that cause the coloration, whilst pure diamonds (which are exceedingly rare) are perfectly transparent and colorless. Diamonds are scientifically classed into two main types and several subtypes, according to the nature of impurities present and how these impurities affect light absorption.
Color intensity scale

The Gemological Institute of America (GIA) uses a "D" to "Z" scale it developed for grading the color of "white" (non-fancy colored) diamonds, where "D" is colorless and "Z" is yellow:
colorless: D, E, F
near colorless: G, H, I, J
faint yellow or brown: K, L, M
very light yellow or brown: N, O, P, Q, R
light yellow or brown: S, T, U, V, W, X, Y, Z
