My Style Adjuster chrome extension uses sliders to change colors, but what makes it good is that it changes the color of a CSS property value in the page, as you slide the slider, while looking at the thing that the color applies to. (It does dimensional values also.) Sliding is better than clicking, because you can't click on something without actually looking at it. But once you've started sliding a slider, you can continue to slide it without looking at the slider.
