This is a gray card created using pure RGB colors in Corel Photo-Paint. I got the settings by scanning a Delta card and then blurring and reblurring the heck out of it. Results? Each color was right around 100 on the RGB scale. The spectral range for each color is very narrow on my card. Use it for white balance, too.
You can make a superior "card" over Delta and Kodak because it has even tonality instead of a lumpy and shiny surface. Put it on a good quality matte paper, or inkjet to fabric! If you use a 90% reflective paper, you now have the flip side of a Kodak Gray Card.
