Bad color on web

[SmallBear]

After I make adjustments on my image and upload it on the web I can get these yellow and blue looking areas that look bad. Does anyone know the cause of this?

My guess is that it's caused by jpg compression - try increasing the jpg quality.

You may have to use a very high quality setting, which could mean quite a large file size.

Alternatively, try using PNG instead, which will probably mean an even larger file size.
