Here we would like to add a color fading to single characters and whole text. It should be possible to use the shaded text within normal text, without an additional border and aligned at the normal text base line.

We define a command \fadingtext[<color options>]{<text>} and furthermore a style fading text for defining preset colors.

\phantom is used to define a place holder node, we use the same node for aligning at the surrounding text’s base line, and this node is then shaded with the previously defined fading.

The example shows, how the style is set. Note, that the middle color has to be set as the last one. So, if you change a color later, re-set the middle color (or it’s removed).

This example was written by Elke Schubert on TikZ.de.
