I was already on grayscale too and it worked. I also wonder if setting c, m and y channels to Quantum.Max with EvaluationOperator would generate same result without changing color type to grayscale....

You could set the values to zero if you want to keep a CMYK image but I am not sure if that would create the same result. You can also set your image to Grayscale and then back to TrueColor right...

But when a ColorCMYK is created from a Color.Cyan, its c value is 0, which should be the max value for cyan. I am a little bit confused here.

It looks like the normal font render engine does not support this. You could use Pango for this: MagickImage label = new MagickImage(); label.BackgroundColor = System.Drawing.Color.Black;...
