Hey I remembering seeing a tutorial for either photoshop or clip studio (don't remember which sorry) about a fill setting that changed the colour a little with every click based on what you had set as foreground colour - anyone know what I'm talking about?

This is one of the threads - thanks @BraedenRaymer (and Tamra!). Remember one involving scales on a snake too, though. https://twitter.com/TBonvillain/status/1132441573105590273?s=20
