Chromatic Tooltips

Update v7 - Reshaded:

• reverted v6 changes
• fixed an issue causing background textures to be stacked on a tooltip
• added proper shading to background and frame textures

This update also comes in a v7M (Mystical) variant which is more moody. It uses darker textures and is closer to the style of v5 & v6.

[Reupload due to Modrinth having had issues & to add darker background to v7M which only had a darker frame previously.]
