The diamond color has a big impact on its appearance. Due to the many prismatic facets a colorless diamond will have much more "fire" ( will reflect more light ) . If color is present in the diamond this ability to reflect light will be reduced.
This is the main reason why the most valuable diamonds have little to no detectable color.

Diamonds are graded under very precise viewing conditions and often compared to a diamond of a known color grade to ensure very few differences within a color grade.
A diamond absent of color is grade ‘D’ and the more color that is present in the diamond, the further along the alphabet it’s grade travels. Diamond with grade ‘Z’ will have a light yellow or brown tint, and therefore will not reflect light as well as a colorless diamond.
Fancy colored diamonds, although most are irradiated and color enhanced, do not follow this grading scale, and often are less valuable because when naturally colored they are extremely rare. The most common color grades are G through I, as they are more abundant in nature, and thus much more affordable.
Although diamonds of these grades does have a hint of color, it generally isn’t visible to the naked and untrained eye.
Likewise, diamonds graded J through M may have a very faint hue of yellow, but with the right jewelry piece and diamond cut, the color may look less obvious (although it barely visible is to begin with). White gold or platinum settings usually require higher grade color diamond, whereas a yellow gold setting takes away from the yellow tint of a lower grade diamond.
Most jewelers use the GIA Diamond Color Grading Scale, and it’s recommended for customers to do the same to better understand the subtle differences in color a diamond may have, and to better assess the quality and value of a diamond.
The diamond color scale begins at D (colorless) and ends at Z (light yellow)
D and E colors are considered 'Exceptional White + ( D) and Exceptional White ( E). To the naked eye, any color above (I ) color can be considered colorless. I and J colors carry a slight trace of color ( generally a slight yellowish tint ).
Any color below J has a Clear trace of color ( a non negligible yellow tint ).
It is imperative to have comparison brilliants in order to grade colors visually. It is important to have the low ( or high ) end of each color, in order to match the diamond in question to its right color. It is also important to compare diamonds under 'white light' and against white background, in order to be accurate.
Compared to other shapes , brilliant round-cut diamonds appear brighter due to greater light reflection.
If you prefer a colorless diamond you should choose a stone in the D-F range with fluorescence rating of none or faint.
Near colorless diamonds with a rating between G and J provide excellent values as their color is undetectable for the untrained eye. These diamonds are perfect to set in platinum or white gold metals.

Fluorescence, the effect ultraviolet (UV) light has on a diamond, is an important consideration when selecting a diamond. When UV light strikes a diamond with fluorescent properties, the stone emits a glow (usually blue) ranging from very faint to quite strong. Colorless (D-F) fluorescent diamonds sell at up to a 15% discount since the fluorescence is perceived as a defect.
