Webpage to create arts for nincat

[BeyondMagic]

It's hard to create arts with lots of escape characters in the terminal.

The solution is to build a site to create arts for no colours, 16, 88, 256 and RGB, just with the colours and then when the user wants, it would share the output code.

Two options with this, either a:

terminal app.
very simple JS + HTML site, preferably, without any framework.

I'll pin this because it's very important to help creating new arts.
