Minecraft – Why is everything in minecraft opaque red and blue

Please uninstall your current java, which includes removing ALL files related to it, such as the part that you put in your Minecraft folder (Which you weren't supposed to do, as it probably messed up the path). Then install java again from the Java website

The launcher has 2 flavors. A java based installer and a non-java based installer.

Both version install the launcher. Once that is done the launcher and the game do require Java. Given your post I would recommend that you download Java 8 for x86-64 if you do not already have it.

When you download the launcher installer be certain to ONLY download it from minecraft.net after logging into your account. If you download it from any other site or attempt to use a 'cracked' version then I wouldn't expect it to work and may Notch have mercy on your soul.

As with the game, be certain that you download Java Runtime ONLY from the trusted site.

If you have errors with Java 8 x86-64 then I would begrudgingly suggest uninstalling and installing Java 7 x86-64 instead.
