Colors, too little options

Hi!
When trying to make some graphic enhancements to my headings etc. I'm trying out colors for backgrounds, lines etc.
The color-pallet is just very limited. Especially when wanting colors in the the light area, towards white and light grey.
I have relied on Open Office for many years, but now I feel I need to look into Microsoft Office or something to get my job done.
Thanks!
