Would love to be able to make a lime green metal wall next to my crimson red wood room in my space station! One way to do this would be to give the ability to craft coloured blocks, but a less clunky way might be the ability to craft Paint items with so much ammo built-in to the item (so you would make a purple paint can with 250 rounds, allowing you to paint up to 250 squares purple). Smiley faces, rainbows, and peace-signs abound! Of course, this would need to be applicable to all normal, background, and foreground (if implemented) blocks And yes, this could lead to people painting profane symbols online, but those same immature people are just going to build the same symbols out of blocks anyway imo
I like the idea, but the type of the blocks you painted should still be visible. So if you paint some of your wood in a silver like iron and someone lays a fire without knowing what he did, you're house is done for! Also, I want some nice ways to paint my blocks, like a colour bomb! or a paint gun! or a colour grenade!
All of those things would be amazing I love it here, everyone just builds on everyone's ideas. If they implement half of the suggestions on here this game will be an instant classic.
... hm, I don't know. Paint doesn't seem like it would fit in the art style of the game. But any equivalent, to that I say: yes. That is an amazing idea. How about... colourable lasers ? That would be cool . (Let's parteh with disco lazorz)
