My color descriptions are invariably bad as I have made the inane choice of having nice and cosy, rather than good and efficient lighting in my home...
The WSET uses the following order to describe the color of a wine (reproduced from memory).
Core: Depth of color (light, medium, deep, opaque), Hue (lemon green, ruby, tawny, garnet, etc.)
Rim: Width of rim (thin, medium, wide), hue (watery, purple, ruby, garnet, etc.)
So you end up with a description like the following:
Deep ruby core with a medium garnet rim.
