NEOchrome Master is an unofficial improved version of the NEOchrome graphics editor for Atari ST.

It apparently has at least two native file formats:

• .NEO - An ILBM file with a "RAST" chunk (or chunk-like segment?).
• .RST - Probably just contains color data, not an image.

Specifications

• There is some information about the formats in the neochrom.txt file included with (at least some copies of) the NEOchrome Master software.
  • A copy at the Atari Forum Wiki
