About this Mod
This mod fixes bug report MC-132961. This bug causes the colour changing text that says which disc is playing, to suddenly stop changing colours. In horror I quickly fixed this bug by making a small change in the code. This worked, but still, I was not satisfied. I tried raising the chromacity, but it just didn't look quite right. Most of the animation was taken up by blue and green, neglecting the colour spectrum's full beauty. This led me into the rabbit hole of perceptual colour spaces.
After countless hours delving into the intricacies of human color perception, deciphering mathematical equations, and extensive coding, I proudly present the perfect color wheel, with each hue is in its rightful position. And now, with this mod, you can enjoy these colours in the action bar for 3 seconds every time you play a music disc.
If desired, you can customize the mod's default settings to:
- Extend the duration of the action bar display.
- Adjust the animation speed to your preference.
- Enable the colorful text to appear e.g. during a player's attempt to sleep through the night or whenever an action bar is triggered.
- Make the action bar colours extra vibrant.
