   When I used this to try making the font color be Navy Blue but it end up as a bright blue.  Why?

        private readonly Color _argbColorIsNavyBlue = Color.FromArgb(35, 35, 142);

	Is this syntax from QuickPDF... i think no? ;-) The data should make navy blue - dealing with online rgb generators make it. Think there are still some settings before having influence on the color?
	Cheers, Ingo

	var argColorIsNavyBlue = Color.FromArgb(35, 35, 142); // .NET Color pdfApp.SetTextColor(argColorIsNavyBlue.R, argColorIsNavyBlue.G, argColorIsNavyBlue.B); // Passed on RGB value to Quick PDF's SetTextColor

	QP.SetTextColor arguments should be Double values between 0 and 1.0. I suspect that Color.R and friends are bytes, but I am not that familiar with C#.

	QP.SetTextColor(35.0/255.0, 35.0/255.0, 142.0/255.0); // looks like Navy Blue to me!

	Okay, another question. How come the color Red works but not different Green color? QP.SetTextColor(255.0/255.0, 0.0/255.0, 0.0/255.0); // Red QP.SetTextColor(0.0/255.0, 128.0/255.0, 0.0/255.0); // Green Edited by fletchsod - 18 Jun 21 at 5:14PM

	Please clarify what you mean by 'different'. For light green you need to start with white and reduce the red and blue. What you show should be darker green. For selecting colours I always go to an application like Paint.net with a good colour-picker that I can adjust, and which then displays the RGB and HSV values. Does this not paint correctly in QPDF when you divide the values by 255?

	Post the sample code here that works for you when you tested it. Ignore the comment regarding different green. That remark comment is wrong but my post comment is correct. I updated the post to remove the word "Different". Thanks. Edited by fletchsod - 18 Jun 21 at 5:16PM

	Sorry, I am not a C# user and I cannot test your code. We are all users here. I just went to the Foxit PDF Library Dashboard, found the Text and HTML / Draw Text sample script, then added one line near the top reading QP.SetTextColor(0.0, 0.5, 0.0); When I ran the modified sample script, it came out green, a bit darker than with 1.0 as the second parameter. These sample scripts are an excellent way to test QP functions quickly. If things work in the scripting, you then just have to change the syntax details to your own programming language.

	I don't mean C# example. Just the Quick PDF example. Ok, seeing your example, I know what the issue is now. It works now when the 0.0 was used instead of 0 in my case. I think the C++ Quick PDF component internally see things a bit different. Thanks.
