(MoveAlong's still)
Not that I'm being pedantic, but it's as I thought - a solid yellow. You need more elements to accurately replicate a crawl - the characters in a real crawl have some characteristic burn, and there's also a faint red drop shadow. It took me a while to understand why I couldn't match a crawl just by tweaking colours.
Unfortunately my crawl making process isn't suited to being used by others...
