I just can't imagina any other coler that would look good with green and blue :/
Where do you excactly mean that i should use the white color?
And do you think that the text would be easier to read, if i used a "fatter" font? (or made it bold)
Thanks for your replies untill now. - Just keep looking... And write all your ideas
Ok, taking another look....
Changing the font color for the main text would help, making it a base color (black or white). Changing the font may help too. If you don't want to add white you could change the shades of the blue and greens you're using. Making a white background could possibly make a dramatic difference though.
