I know what a gradient is, and I can create one,
but gradients with default settings look unnatural and outdated:
How do I achieve a professional look with seamless gradients:
It's the Spark theme from the Adobe Flex Framework.
I've found glass button tutorials, but it's not what I'm looking for.
How do I create seamless gradients that are barely noticeable?
It simply takes less drastic moves in value/color. Rather than a white to black gradient, using a 15% black to 25% black would give a smoother gradient over a small area.
