I’M INTERESTED IN THE EVANS HYDRAULIC SERIES FOR MY KIT. IS THERE ANY SIGNIFICANCE BETWEEN COLORS?

Yes there is. Ply thickness is defined by color:

Black  6.5mil + 7.5mil
Red & Blue  7mil + 7mil
Glass  6.5mil + 6.5mil

A thicker ply provides you with more durability, volume/body, decreased sensitivity, and increased attack. A thinner ply provides you with with less durability, volume, and attack, but an increase in sensitivity.
