My goal is to change the color of your choice while keeping:
-more or less large white dots
-the proportion of gradations in the same places and the same nuances

Here is one of many ways to do this:


Add Color ramp node - use it to adjust whites/blacks
Add Mix node set to Screen - it will filter out the black parts
Connect RGB node and select your desired color
