I don't think I have the energy to design and execute actual keycap sets that can be sold on Massdrop, but I have some ideas that I think would make really beautiful keycap sets. If any of you want to take these ideas and turn them into keycap sets, feel free to do so.
Matcha, Coffee, and Chocolate - This set is inspired by the matcha green tea desserts that are so yummy, and are often paired with chocolate. Add coffee to it and it's a gorgeous and tasteful set of color palette using matcha green with dark brown legends for alphas, dark or medium chocolate browns with match green legends for modifiers, and cappuccino/latte light browns for accents (Esc, Enter, arrows, etc.).
Eva-01 - If you have watched Evangelion, you know exactly what I'm talking about. That iconic and striking purple, green, and orange color palette. Purple alphas with green legends, green modifiers with purple legends, and orange accents (Esc, Enter, arrows, etc.).
Rocky Road - Almond beige or golden caramel with dark or medium brown legends for alphas, dark or medium chocolate browns with beige or caramel legends for modifiers, and white marshmallow for accents (Esc, Enter, arrows, etc.).
