Colored banners other than black are being black

So, when I put a banner in a loom and color it, it turns out black, and when I do 2 patterns, it still ends up being one pattern...

I expected it to be the same color, like "yellow banner", "blue banner", when I was going to put a pattern on it in the loom

Then, when I put the banner through the loom, the banner turned black, and also, when I put another pattern, the banner pattern still ends up being one pattern...

1. Fix the "turn black banner"(when the banner turns back) to the color chosen
2. Fix the problem where the banner is only on one pattern when you want to put 2 patterns
