as for the color, i have to agree with TEG, coz my evoo batch ended up being similar to yours (greenish/yellowish color).
i don't suggest CPOP-ing with silicone mold, unless you're willing to watch it like a hawk all the time. it can take only minutes for the soap to rise and all is ruined. been there, done that.
as for the pattern, hmmmm... you said it yourself that the soap was starting to rise, and you took it out of the oven. maybe that's the cause. who knows what was happening down there. i'm a bit baffled myself. sorry can't help you more here. perhaps someone more experienced will chime in.
