An example - Let's say this color is on your screen:
(click the rainbow button to find other colors).
Let's say that color reminds you of cheese fries. Yum.
Click the "Add Tags" button to add a tag.
Tag added! (actually 2 tags in this case).
That's pretty much it. Oh, here are some guidelines:
You can right-click tags to remove them:
It's not actually gone for good. Tag history is preserved.
If you click the "more" button, you can see a list of all the tags ever added or removed from a color or scheme.
Removed tags in the history list can be re-added by right-clicking them.
Color schemes are much the same. You can add and remove colors (click a color to remove it).
When you change the colors from an existing scheme, it creates a brand new scheme. The new scheme won't get "saved" until you add a tag.
