Header and SubHeader Color

Hello,

I would like a different format for my header and subheaders.
Is this possible?

You can use for example:

advstringgrid1.FixedFont.Color := clRed;
advstringgrid1.FixedFont.Style := [fsItalic];

In a same Grid i want a different format for my header like (red and italic) and an other format for my subheader (blue and bold)

To change the font color with a property , You can use

grid.FontColors[col,row]: TColor;
