If you have a large format printer, having a good color chart is extremely useful to find color matches to physical samples. However finding a good color chart is hard, Standard charts such as Pantone donít have enough colors, and standard CMYK color charts are not logical.
Hue based colors charts are superior to standard RGB or CMYK color charts:
Hue based charts are easier to find a color, as itís how your brain thinks about color, lighter-darker, more or less saturated.
The lightness and saturation are nonlinear and are in finer steps in lighter and grey colors where the difference between colors are more noticeable.

I have a passion for science, technology, computers and design and worked in the design and print industry for the last 20 years. I‚Äôve been a graphic designer, web developer, programmer, print operator, manager and business owner. During that time I‚Äôve discovered that a lot of the design prepress work is a manual repetitive process which is prone to human error and rather boring. So to make my job easier I developed a lot of automation software which has now developed into PowerScripts.
