Pink...
I Thought it was Purple???
Anyway, maybe the colour in question could of been the closet colour to "As" well, as keeping it close to Grey...
While maintaining a similar Brightness of Fluorescence which can be used on Kids toys for Visual Stimulation
Or it could be due to someone trying to differentiate it (or/and save money) by adding Blue to the Red "which makes Purple" to Highlight the shades of White, Light Greys and Dark Greys ??????
