Lol,
I looked up what mauve should be and found;
"Mauve is more grey and more blue than a pale tint of magenta would be."
Then I found;
"Magenta is not found in the visible spectrum of light. Rather, it is physiologically and psychologically perceived as the mixture of red and blue light, with the absence of green."
So in a nutshell, the 135 already has or might have a Mauve-ish bit of string fitted, just that we can't see it
