I did a cereal mash with "Fruity Pebbles". It had a really nasty color while fermenting, like sewage. It ended up clearing up and looking more like beer by the end. Biggest problem I had was all the tub that ended up in the bottling bucket. It could not be avoided no matter how hard I tried. I don't know if that contributed to the off flavors or not, but it had a aluminum after taste to it. Some of the fruity flavors did show through, but I don't think that will be something I'll do again. Glad I only did one gallon.
