Keeping colors in proportion

In InDesign, you want to modify a color slightly, keeping it in the same basic hue. Maybe you've duplicated a color and need a slightly lighter or darker color to complement your design. You double click the swatch in the palette and you get this:

Moving the sliders individually will radically alter the color. You need to move all the sliders at once, keeping them in proportion. And InDesign has a way to do this. Simply hold down the shift key as you click and drag the sliders. They will all move together:

Look at the numbers in the screenshot above. I simply clicked on the Cyan slider and moved it to the left while holding down the shift key. All of the sliders moved in proportion. Cyan went from 72% to 62%. And the other colors moved, too. Here's another screenshot where I've moved the Cyan slider to 52%:

And the same trick works in Illustrator, too. Just hold the shift key to move the Color palette sliders together. It's a simple and powerful way to adjust your color palette.
