From within LT the only real option is hatching, solid hatching can be set to any color you want, you can set transparency, or use a pattern and scale it to produce some effects with overlapping hatches, there is even gradient hatching, or possibly the use of clipped images, but to be honest whatever you do it looks flat and boring, unless you are a real artist and have hours to spend. LT just isn't designed for that type of presentations, I won't say it can't be done, I do things that can't be done. It's just not the right tool for the job.
