Could be your monitor or your eyes. The red/purples are between 12:00 and 1:00 for me, the next two (between 1:00 and 3:00 are almost interchangeable for me, and I agree that the blue one between 3:00 and 4:00 has too much teal in it.
I'm also worried about the complexity of the color choices. Many of my roses are classified as apricot blends. Rose growers know what "apricot blend" means. It's a blend of colors that includes several shades of apricot, peach, cream, tan, light orange, and sometimes light pink. Would I have to enter 9 or 10 numbers to convey the meaning?
