^ title. I don't have any experience with coding in SMAPI but I want to release an aesthetic overhaul of the Junimos, to something cuter and more pastel, but I know the game automatically assigns colours so that they all look different. I just want to know if it's possible to override these base colours using a SMAPI mod.
Yep. Each Junimo has a color field, so the SMAPI mod would just need to detect when a Junimo appears and change its color. See the modding documentation if you're interested, and feel free to come chat with modders on Discord if you need help or have questions.
