So I coded a customized palette-creation script but when copying palettes to paint.net and other pieces of software I notice something weird:

Occasionally when I create a colour it will slightly tweak the HSB. Say if I create (45, 80%, 94%) it changes it too (43, 80%, 92%). Is this because those HSB colours are equal? Why does this happen?

Thanks!

    Illustrator also tends to this. Extremely annoying. Isn't this because the colors are stored as RGB or CMYK? I always assumed these deviations occurred from the conversion of hsl to RGB and back. – Ideogram May 14 '17 at 12:46

They are not equivalent:

The upper half is the first and the lower is the second.

I do not know, why your program does such changes. One possiblity is that you have activated some option that restricts your selectable color range to some predefined palette.

  • RGB to CMYK conversion? – joojaa May 14 '17 at 14:06
  • I didn't activate any option like that, sadly =(. Thanks a lot for your help, they are indeed not equivalent =) – Gaspa79 May 14 '17 at 23:00
