I'm trying to get a color value and adjust it by xx% (darken or lighten the color) Is there any build in classes for this like: Color NewColor = AdjustColor(Color.Red, -10%); OR better, Is there a FillRectangle function that looks like a sylinder with lighting effect but without the rounded top and bottom Try to use DirectX or OpenGL instead. > I'm trying to get a color value and adjust it by xx% (darken or lighten > the color) > Is there any build in classes for this like: > Color NewColor = AdjustColor(Color.Red, -10%); > OR better, Is there a FillRectangle function that looks like a sylinder > with lighting effect but without the rounded top and bottom  SignatureVit Zayko Tx Vit, However I'n not familar with OpenGL. Do you have any samples available using it? I don't want to use DirectX - (IHI) Best regards GTi Sorry, I'm not an OpenGL expert either. But this is what I found: http://www.codeproject.com/csharp/csopengl.asp http://csgl.sourceforge.net/ Hope this help. > Tx Vit, > However I'n not familar with OpenGL.

I only want to generate some simple bars on a webpage. Putting on a lighting effect was only to make it nice-looking. Regards, GTi See the article on RGB and HSL in the GDI+ FAQ.
