Wanting to learn how to recolor skins for my main champs — where should I start?

Hey everyone!

I'm really interested in learning how to recolor skins for my main champions, but I'm a complete beginner when it comes to custom skin editing and League modding.

Could anyone recommend some good tutorials, guides, or communities to get started with texture recoloring?

A few questions:

• What software/tools do you recommend for extracting textures and importing custom skins?
• What software do you use for texture editing (Photoshop, GIMP, Photopea, etc.)?
• Are there any active Discord servers or YouTube channels dedicated to League modding?

Any tips or resources would be greatly appreciated. Thanks in advance!
