No it's not, you 'I only register primary colors'-cisgender male mole! I have sometimes issues describing something as purple, violet or lilac. Even Deep Purple weren't always sure whether they weren't Deep Lilac or Deep Violet, the inconsistency has always bugged me no end.
The issue is confounded in German because we translate "purple" as all kinds of varying violet'ish shades ...
The German term "
purpur" does ironically not correspond with the english term "purple" - the color us Krauts envisage as "
purpur" is closer to a shade you guys would assure us is red-violet.
But there is a scientific explanation for the difficulty in discerning those shades: What we describe as purple, violet or lilac are color shades not really mirrored in the visible light spectrum, they are mostly solely a creation of our eyes and brain and cannot be simply attributed to a specific nanometer wavelength. Rather, these color shades stimulate both our photoreceptors for
red and those
other photoreceptors for
blue at the same time - everything else happens in our brains.
Too add to the confusion there is also a true spectral color called violet:

Purple is closely associated with violet. In common usage, both refer to a variety of colors between blue and red in hue. Historically, purple has tended to be used for redder hues and violet for bluer hues. In optics, violet is a spectral color: It refers to the color of any different single wavelength of light on the short wavelength end of the visible spectrum, between approximately 380 and 450 nanometers, whereas purple is the color of various combinations of red, blue, and violet light, some of which humans perceive as similar to violet.But then a guy working for a joint called Seattle Lighting should really know (t)his stuff, I'm sure (s)he'll explain.
