Colour variations with BB Code

[NuttsnBolts]

So I noticed something weird

text

>text

[color=green]text[/color]

[color=green]>text[/color]

Image in case others don't see it.
vvvvv

Why is the colour changing when it's still green?

I think it's because the > symbol triggers some sort of different coding when you start a line with it. For example,
Hi
>hi
I don't know specifically what coding that triggers, but it does it regardless of color.
Hi
>hi
