Change Colour on Chapter/Section headings {Lyx}

Question

I am using Lyx and Layout report for my thesis. I would like to change the colour of chapters sections and subsections (only the headings) from black to blue.

I attach a screenshot in order to understand what colours i am trying to achieve only on headings (Chapter /section and subsection )

Also is it possible to change the colour of table of contents to blue ? (again only the heading)

Answer 1

You can use the package sectsty to do change the headings, and xcolor to get the colour definitions.

For example, add to your preamble (Document --> Settings --> LaTeX preamble) the following:

\usepackage{xcolor}
\usepackage{sectsty}
\chapterfont{\color{blue}}  % sets colour of chapters
\sectionfont{\color{cyan}}  % sets colour of sections

You can use colours predefined in xcolor (see manual), or define your own, e.g.

\definecolor{MyBlue}{rgb}{0.1,0.1,1}

Put such definitions in the preamble as well.
