ColorMode

The color mode of an sprite or image specifies the internal structure of each pixel. You can see the Color Mode section in the Aseprite docs for an introduction about each color mode.

ColorMode.RGB

You can use this color mode to create RGBA sprites and images.

Each pixel is a 32-bit unsigned integer where each component (Red, Green, Blue, and Alpha) uses 8-bit (values from 0 to 255).

ColorMode.GRAY

You can use this color mode to create gray sprites and images. Known as ColorMode.GRAYSCALE in previous versions.

Each pixel is a 16-bit unsigned integer where each component (Gray and Alpha) uses 8-bit (values from 0 to 255).

ColorMode.INDEXED

You can use this color mode to create indexed sprites and images.

Each pixel is an 8-bit unsigned integer (a value from 0 to 255) which indicates the specific palette entry which the pixel refers.

ColorMode.TILEMAP

Special color mode used for tilemaps, where each pixel is tile reference in a tileset.
