Change anti alias colors?

Hi!

Is there a way to control what colors are used for anti aliasing? Im working at an image using a Commodore 64 palette. 16 colors.
For example if on a black background I paint with cyan. The anti aliasing is using grey colors. Is there a way for me to get it to use the two blue colors in the palette instead?

Something like the below picture
