Pink and purple usually make lilac, lavender, or a lighter mauve tone depending on the exact shades and how much of each color you mix. Wikipedia’s purple entry describes purple as a color that sits between red and blue, which helps explain why mixing it with pink often shifts the result toward softer pastel shades.

What changes the result

  • More pink gives you a warmer, softer pastel.
  • More purple gives you a deeper lilac or mauve.
  • Adding white makes the mix even lighter.

Simple example

If you mix a bright pink with a medium purple, you usually get a light purple-pink color rather than a strong new color. The exact shade depends on whether the colors are paint, dye, or digital colors, since those mix differently.

Note

“Quick Scoop” on your post fits this as a short color-mixing answer, but the safest one-line answer is: pink and purple make a light lavender/lilac shade.
