How to link my ColorDialog Colors to Excel Colors ?

[Pierre]

Hi,
Allowing my User to set Excel charts colors in my app with the help of a
ColorDialog,
I'm facing the following problem : the ColorDialog Colors does not suit with
the Excel ones.

So, here is my question :
Is-it possible to change Excel colors ?
Is it possible to set ColorDialog Colors with the Excel available ones ?
or Whatever possibily...

All help will be most welcome.

Thks.
