When setting the style.color of a range on a sheet it appears that no matter what Drawing.color.FromArgb values I set it to it will only set the colors to web colors (the full spectrum is not available like it is from within Excel). Am I doing something wrong?

Thanks.

the line of code I'm trying to use is the following:
coverSheet.Range(2, 5, 2, 9).Style.Color = Drawing.Color.FromArgb(55, 96, 145)

but the actual output in the excel file gives me the color with the following RGB value:
R:51 G:51 B:153

What is changing the colors? How do I get the {55,96,145} values to stick?

I referenced "web colors" in my post because in Photoshop's colorpicker if I enter my intended RGB values and then check the "only Web colors" checkbox it gives me something very close to the {51,51,153} color value.

thank you for your time.

Hello,

Thank you for your additional information.

Please try to use following source code to set excel pallette color, then you color can not be changed.
Code: Select all
workbook.ChangePaletteColor(System.Drawing.Color.FromArgb(55, 96, 145), 9);


Please let me know if you have any questions and concerns.

Best Regards.

This appears to have worked, although I don't understand what it does. Do I have to do this for every color I want to use in my workbook?
