I've really had to scramble for some of these images for the rainbow challenge. It helps to know what colors will turn into what when inverted. A color wheel helps - a lot - so you can see their opposites.
@johnfalconer Thank you, John. Find a color wheel online that you can use to see what you want to invert and what it's opposite will be when you invert it. You can then use your sliders to adjust the tint.
Thanks mags. I have a colour wheel app so I’ll look at that.
@wakelys Thank you, Susan.
