## Detailed Description

The color data type is responsible for providing colour conversion features.

Color modules provide the actual functionality, so different colour management modules may provide the application with different services (for example, colour profiles).

## Typedef Documentation

## stp_color_t

typedef struct stp_color stp_color_t
