As you can see you only have one slider in the Colour palette which corresponds to the colour that you have selected in your Swatches palette. Next to the slider you have the letter T, which stands for "Tint" (don't get confused with the bigger icon with the "T" which stands for type). So now that you have specified your swatch in your Swatches palette, you can specify the tint of your swatch in the Colour palette. As I explained earlier, you can specify a new tint right in your Swatches palette, so you can apply the same tint over and over. Another option is to drag a tint that you made in your Colour palette into your Swatches palette and you now have a new swatch.
