Color spread or texture particlesgpu

Hi i’m playing around with the particlesgpu shader by dottore, in particular with ParticlesGPU_2d_Dynamic_FieldTexture, and i was wondering if it’s possible to color the particles in different ways instead of having many all of the same color…i tried to spread the color pin of the particlesgpu_2d_dynamic_constant but with no luck.
Another question would be, is it possible to make them take the color of a texture (in their birth moment) so for example i can simulate the color spread of a galaxy (see attached photos)?

thanks for any tip/advice!
