5 Checking the values
I frequently check the colour values of an illustration by eliminating saturation. It’s easy to do: from the menu bar, simply choose Layer> New Adjustment Layer>Hue/ Saturation to add an Adjustment layer and then drop the Saturation level down to -100. Generally, foreground objects have lower values and backgrounds have higher values. Even though in this case the space is separated into just two elements – the character and the background – the proper order of values must be applied to the character, too.
