Here's a great trick that I use on a daily basis for quickly tinting or mixing colors on the fly: select the vector object with the color you want to alter, then press and hold Ctrl and click a color swatch in the color palette. This adds 10% of the color swatch to the fill of the selected object. It also works with outlines if you right-click a color swatch.
