When I think of pink, the first thing tha comes to mind is the "hot pink" used in breast cancer awareness and "girly stuff." This color is a mix of red and blue, putting it just shy of purple. I think magenta is the more correct name for it, but I'm more likely to attach pink to this color than to light red. Native English speaker, but there are probably other factors influencing our perception of colors.
Yes. Pink to my eyes is a kind of watered down red. Do you consider it any more different? Ie the kind of difference you get from purple vs yellow, or red vs green?
