Manual Content: Filter Effect Types page doesn't specify what values are used for colour arrays

[KormexGit]

What is the bug?

The page on filter effects says that colours are passed as an array with this format: [r, g, b, a*]. But what it doesn't say is what the rgb values should be. In some situations, rgb values go from 0-1 (like in shaders), and in other cases, 0-255 (like make_colour_rgb). It'd be nice if the page mentioned which of these the argument is expecting, since I could see it being either one.
