Shader code -->

Might be useful, looks somewhat down the road, just pull the Time slider and everything glides around moves over fbm modulation.

Now, this is a characteristic simplex modulation, where both compressed bands and plamages is a theme, you can pipe the shader through a Color Correction node and work on hue/saturation if you want to tweak hardcoded color set.

You could also try adding noise->rampRGB->specular_color or just use your texture map-> specular_color.
