Hi Stuart,
first, you can play with the ColorPalette (SecondaryDark color is used in the tiddler titles and section headers). You can use any color picker out there (
example), pick the color, copy the Hex code, and paste it instead of the current #841 value (it's short for #884411, so don't worry about a different length).
If you'd like to style those separately (use different colors), than you'll need to add to StyleSheet something like:
/* tiddler titles */
.title {
color: red;
}
/* heading created with !heading syntax */
h1 {
color: #123456;
}
/* heading created with !!heading syntax */
h2 {
color: #654321;
}
/* ... */
Best regards,
Yakov
