Spectrum Next palette for graphics artists

Postby Stefan123 » Mon Mar 30, 2020 6:39 pm

Here is a palette that may be of use for graphics artists for the Spectrum Next:

This text file describes the palette in more detail:

The palette contains several visualizations of the 512 color Spectrum Next palette.
Open the palette image in your favorite paint program and use it as a color picker.

I hope you like it :)

Since a few people wanted a 256-color version of the palette I wrote about a few days ago, here it is:

Note that this version of the palette looks a bit asymmetrical. This is because the RGB332 color space is non-uniform where the blue color component is only half the size of the red and green color components. This irregularity becomes very evident when visualizing the palette.

When converting images to the Spectrum Next, much better results are obtained by using the 512-color palette. However, for some types of games it's convenient to use the standard 256-color palette.

The 256-color palette files (.pal, .act etc) have also been updated:

Previously, these palette files used [0, 85, 170, 255] for the blue component but have been updated to use [0, 109, 182, 255] instead. This is done in order to take into account that the RGB332 colors are auto-extended to RGB333 colors by the Next hardware when being displayed.
