Hi Jeff Mather,
I’m a student who is doing my final year project about colour blindness. I just download you coding for protanopia and deuteranopia as my reference for my software. but may i know how you do the calculation both two blindness to get the color anomalies value? because i want to do for trinatopia type.

Please do email me the guide. Thank You so much.

Regards,
Aremint

Vijay: I’m not aware of a method for swapping the color table (colormap) of an image in Photoshop. That’s not to say it’s impossible; I just don’t know how one would do it. If you can figure that out, then it should be very easy.

I think it’s worth noting that the important thing is to use color universal design when it’s possible that the information in your graphic is difficult to use. Unless you’re using your photographs as part of a larger informatics project, it might not be necessary to simulate them this way at all.

Hello Jeff

I”am a photographer I would like to thank you for putting across the article on the net and I curse myself why I never thought of making pic for such people all these years, I will make an effort to convert the rgb files into protanopia,deuternopia files.

Can you help me step by step how to do the conversion in photoshop.

Thank you once again.

Regards
Vijay
