FLUX.2 supports precise color matching using hex codes. Useful for brand consistency, design work, and any scenario where exact colors matter. Signal hex colors with keywords like “color” or “hex” followed by the code, and associate each hex value clearly with a specific object or surface.

​
Basic Syntax

Signal hex colors with keywords like “color” or “hex” followed by the code:

Hex codes work best when clearly associated with specific objects. Vague references like “use #FF0000 somewhere” may produce inconsistent results.
