This idea is borrowed from CorelDraw (Sorry Lucky Clan. There ARE tools implemented better in other apps out there. So I’m offering suggestions here to see if you’re willing to look into this.)
In CorelDraw, when you select a color swatch and long press on the square a popout shows a list of all the gradients from that color allowing you to quickly choose the exact shade of the color to select. This makes it super convenient to select color tints without needing to manually locate the color on the color wheel. In this way you could always get the exact shade when choosing a color. Ask Borodante. Even he’d confirm this is correct. And yes, if you implement this he’ll do a happy dance.
