Greetings,

I’m helping a child out with a project and need some assistance.

I’m fully aware that the colors on my monitor won’t be the same when printed from my home printer and the reasons why, but we’re still trying to get the colors as close as possible to the color on the screen. The monitor is calibrated. After some experimenting I’ve come across a color that prints close enough. There are a few other colors to replicate and I’m hoping now that I’ve figured out the values of the monitor and printer versions of this color that I can replicate the remaining colors in an easier manner than trial-by-error.

Does anyone know of an app where it would be possible to enter the HEX, RGB, CMYK codes of the two colors that can determine a mathematical relation that can be applied to another color to determine the value of X (the unknown color). Like simple math solving for X using cross multiplication - if I know the relation between A/B, then I should be able to calculate the relation between C/X.

Open to any ideas, apps, tools, or old fashioned, manual calculations as well.

Thanks
