Bests & Worsts Reviews from Amazon

I bought this product from Amazon, based on the strong user reviews. I was quite surprised to see what it proposes as "Orange" (Card #21). Please see my attached photo, which shows : - this product's Card #21 ("Orange"), on top of - the "Pocket Color Tool" showing a correct Orange reference hue, on top of - a book with an orange color, on top of - a book with a white cover. The color mixing formula given on this product's Card #21 specifies the "PURE" Orange hue as CMYK (0,100,100,0). In other words, according to this product, orange pigment is an equal mix of pure magenta and pure yellow pigments. YouTube happens to have a video showing what happens when you mix these two primaries : you get Red! Please search on YouTube for the video called "YELLOW + MAGENTA = RED" If you Google the phrase "orange color", the results page has a sidebar showing example swatches and images. None of these match what the 3-in-1 Color Tool presents as Orange. Neither do any of the examples shown in the Wikipedia entry "Orange (colour)". According to the Wiki page, Orange is CMYK (0,50,100,0) -- i.e. 50% Magenta pigment plus 100% Yellow pigment. So this product's Card #21 is off in both the hue and the CMYK values for Orange. All of the above is simply technical justification in support of the obvious: the 3-in-1 Color Tool presents Red as Orange. Another reviewer here has mentioned the same perception. For my part, I can't justify or recommend giving this product any further consideration. I will be returning it. Hopefully the publisher will reality-check everything and correct for version 4. (I am reviewing version 3) I have written to the company asking them about all this. If and when I hear back from them, I will update this review.
