The Ctrl-C keyboard shortcut is one of the most frequently used in Figma. It’s very useful because you don’t have to direct your mouse cursor to the properties panel area and perform a bunch of clicks, which breaks the flow that you are in on the design canvas. You often can just pick a color from your design right there on the canvas.
But it falls short when you are working with color styles, a design system, etc., which is an increasingly common scenario. In this case, you rarely want to pick a hard-coded color value. Currently, when you use the color picker on top of a layer which has a fill that uses a color style, it picks up the hard color value, not the style.
The idea here is very simple: Give the shortcut a modifier which will make the color picker pick up and apply the color style, and not the raw color value.
In fact I’d go another step further and add a thin vertical color styles strip along the side of the properties panel, so that your color styles are always there for you to pick from.
