Splash is a Fabric mod that allows you to customize the colors of your splash screen.
By default, it uses a dark color scheme:
That instantly makes it a superior alternative to the Darker Loading Screen mod for Forge, but that's not all. If you have Mod Menu installed, you can access a configuration screen, which allows you to preview any changes without restarting Minecraft:
The top-left text box is background color, top-right is logo color, and the three extra text boxes on the left side (from top to bottom) are the progress bar outline color, background color, and bar color.
This mod requires Fabric Language Kotlin version 1.3.71 or higher.
