I would have said purple, It sounds better than Violet ( which is a little girly )
Purple is sometimes confused with the more narrowly-defined spectral color violet.
In color theory a Purple is defined as any non-spectral color between violet and red.
Violet is a spectral color (approximately 420–380nm), of a shorter wavelength than blue, while purple is a combination of red and blue or violet light. The purples are colors that are not spectral colors – purples are extraspectral colors. In fact, purple was not present on Newton's color wheel (which went directly from violet to red), though it is present on modern ones, between red and violet. There is no such thing as the "wavelength of purple light"; it only exists as a combination. [ quote : Wikipedia ]
