This is a CAS Background mod that removes the ugly blob circle thing at the bottom and comes in many different colors by simending and pooklet from tumblr! I used their actions to create these pretty backgrounds, so credit goes to them for that! Built with game version 1.53 and Island Living (not required though).

Simending:



Here are the various colors CAS Background, using simending's palette, comes in (click to make it bigger, goes from left to right):
As listed: dark blue, dark pastel green, light grey, light sepia, light violet, medium pastel blue, medium watermelon, medium wine, mint, pastel cherry, pastel hot pink, pastel ochre, purple heather, and turquoise.

Pooklet:



Here are the various colors CAS Background Pt 2, using pooklet's palette from "Project Mayhem - Outdated Colors", comes in; (click to make bigger, from left to right, top to bottom): afterburner, atomic, blasting agent, c-3, c-4, cannonball, combustible, detonator, fulminant, guncotton, hangfire, hazardous, HMX, nitroglycerin, noxious, TNT, torpedo, toxicity, and unstable. The two pictures above show the toxicity package.



ONLY PICK ONE CAS BACKGROUND. You can only have one CAS background in your game at a time! They will conflict otherwise. The zip file includes all the different colors in .package form with each color picture matching the package it goes with. You only need to place the package file in your mods folder! The pictures are just for reference. <3
