Cat Colors & UCD
Color Genetics are a wide and interesting field. Below are several documents to help you in this general context.
You may want to start with "What Color Is My Cat". It is a good starting point if you want to learn what different colors and patterns may look like based on pictures.
If you want a complete picture of the theory behind the genetics and descriptions of colors accepted by TICA, the Uniform Color Descriptions & Glossary of Terms is a very detailed publication. The other documents listed below are little helpers for specific contexts (e.g. "Color Me Red" is a short explanation under which circumstances a cat may be completely or partially red).
