Paint bucket color off

[Ritergeek]

The paint bucket in Gimp 2.10.20 is not adding color correctly. As you can see from the attachment, colors in two of the three rectangles are faded. The bright gold one is pasted in from elsewhere and the paintbrush strokes do properly show color. Same thing with the blue. For whatever it may be worth, I'm running GIMP on a fully updated version of Win 10.

Any idea what might be causing this and how to fix it? The color setting is exactly the same for the brush strokes and corresponding box.

Thanks for you help.

PROBLEM SOLVED!

I have checked tool settings, layer transparency and all the obvious things. I finally discovered that the bucket tool's opacity was only 50%. DUH!
