Guys and gals, I need some feedback on one element of a marking system design I've been evolving for years and testing and refining in regional 2-day events. I need more feedback from more people having some form and severity of the following color-vision deficiencies: Please bear in mind that one problem regarding design for color-vision deficiencies by a normal vision person is inconsistency in the many charts on the web about how colors are seen by those having the deficiencies. Perhaps that arises from the difficulty of describing what people cannot see well or never have seen? The colors in question follow. I've had limited colors to choose from in high quality 4" X 5" flags and have worked hard to select and order them in such a way as to still have a workable system. I know I'm close but I could use a little more feedback. I hope there are no two colors that are indistinguishable. The problematic colors are often istinguishable by shade and intensity differences. Ambiguity should be less, not more, out in strong light with actual flags, so an on-screen view for a test should be pretty good. Let me know if any of you have trouble distinguishing between any of the following colors. Please name the colors you have problems with and try to describe what you see. Identify your specific color-vision deficiency too. I'd rather the feedback be here, in public, thanks, but if you don't want to go public you can PM me. Please don't sidetrack this part of the thread into non-color-related issues. You'll get your chance to critique the broader system later when I publish the system here in the form of a multi page document with lots of illustrations. The system has been real world tested in two regional 2-day events. This latest version will be tested in another 2-day event, this time 10 & 11 November, HPTA, at Buffalo Dream Ranch in Southwest Oklahoma. If I need to change or rearrange some colors I want to do that before I publish the document and before this upcoming event.
