Bits 7-0 = Eight bit colour for the palette index selected by the {{NextRegNo|$40}}.

Format is RRRGGGBB - Note the lowest blue bit of colour (ninth bit) will be set to an OR between bit 1 and bit 0.

After the write, the palette index is auto-incremented to the next index, if the auto-increment is enabled at {{NextRegNo|$43}}. And also the index of {{NextRegNo|$44}} is reset, so the next write there will be considered as first byte of colour.

Read does not auto-increment the index, and reads always the top 8 bits of colour from palette, to read the 9th bit of colour, use {{NextRegNo|$44}} in tandem with value from this register.

The modified palette remains until a Hard Reset.
