Try the palette without teal. Pink, Hot Pink, Medium Orchid, and Purple settle into one neighboring group. Their differences remain visible, but none breaks the shared red-violet pull.
Now return the last two swatches. Light Sea Green and Teal introduce a green-blue note that has no overlap with the first four. The contrast is immediate. Teal is not a decorative ending here; it is the test that reveals how closely pink and purple are related.
