How to change the saturablility of the color in picture

Hi experts :grinning:
I want to change the saturablility of the color in my picture. The only thing I know is like:
h1->setlinecolor()
But the results are quite “light”, especially for red blue green…Would you please tell me how to make the picture more “dark”. :grin:Thank you bery much for your kind help :laughing:

Hi @sdevip1

Depends that you are doing.
For some special cases you can use dark colors

Or you can change line width aka h1->SetLineWidth(3);

Or generate any kind of RGB color like:

auto new_col = TColor::GetColor(0.5, 0.5, 0.3); // R,G,B
h1->SetLineColor(new_col);
