All we have rn is Lagoon and Lavender, and a bunch of other people suggested more. I have my own suggestions based on colors I haven't seen yet.

Heatwave
A rich, earthy orange skin, like the sand of some deserts

How to obtain:
You find the following explore encounter:
"You stumble upon a wide stretch of sand, bright orange in color. It's very far from where you live, colored unlike any other desert you've seen before."
Options include:
- 1 Medlar fruit
- 1 African cucumber
- 1 Bone marrow
- 1 Skin Applicator: Heatwave

Rose
A pink skin, differentiated from the regular pink skin by its brighter hue.

How to obtain:
You find the following explore encounter:
"You smelled the flower before you saw them. Ahead of you is a swath of thorny flower bushes, blooming with exotic pink flowers that don't seem to be native here. Is this some weird human's farm?"
Options include:
- 1 Catnip
- 1 Fuchsia flower
- 1 Dove feast
- 1 Skin Applicator: Rose

Sapphire
A deep, rich blue skin, with an almost shimmery luster

How to obtain:
You find the following explore encounter:
"You wander down a new hole when you suddenly slip and fall into a large cavern with a deep pool at the bottom. Upon closer inspection, the rock walls seem to be embedded with small traces of gemstones and other shiny minerals, whose luster is reflected in the dark water!"
Options include:
- 1 Crumbled fossil
- 1 Longfin eel
- 1 Opal saltlick
- 1 Skin Applicator: Sapphire
