• Plotting CIE color

    From Wahyu Indayani@21:1/5 to All on Mon Aug 10 21:06:50 2015
    I've done my x. y (coordinate CIE ciagram) calculation. I have x variable, and I have y variable. but, what I've to do next is plotting them on CIE diagram.

    How to plot x,y coordinate on CIE diagram with great precision?
    should I do it manually?

    ran across this link where I was searching what medium ROMM was

    https://luminous-landscape.com/understanding-prophoto-rgb/

    maybe ColorSync Utility has a lot of color data visualisation tools

    if anyone knows what medium ROMM is could you let me know?

    I have some experience working with a predecessor of something like PRMG
    and transparency/translucency AgX display materials exposed digitally
    which have more dynamic range the print space

    is ROMM an actual medium and does its gamut handle the range of transparency/translucency materials, maybe materials are not even used
    any more and this is handled by monitors

    its nice to have an actual medium to troubleshoot, the way I read what
    PRMG it is kind of a compromise, is ROMM like this? I realize the two appearance considerations are different
