Make a text file called "profile.tbs" in your main toribash folder.
Go into it, type "lws theblues.inc" (without quotation marks)
Hit save.
Enjoy your new default shader.

Also, my shaders are the best. :U

Warcry has insane ones, so as Pirate. Aikanaro's "Ivo2.inc" is neat either. [Download link in first post]

Meatwad_silver gets kinda overused. I like Meatwad_desert more.
By the way, there are some really neat shaders in the custom shaders sticky in art and videos.

Here are my Favorites ( First post Examples )

Ty Warcry for the alsome shaders, and Nobuddie, TY for the tip ^^

sunrise.inc

green ground and and light-colorded blue sky then it looks like a grassland

Search through this thread, for a one that strikes your fancy. If you don't find one you like, I'd be happy to make you one, no cost. I'm quite adept.

I like the Azurite and Olive shaders in the thread pirate linked. Plus, you can always find blams shader maker script which has a GUI that lets you change the colors with sliders. Its still kinda hard to use if you dont know what you are doing though.
