Generally color enhancement is achieved with a saturation adjustment. It pops the color out on pictures! It is easier to enhance than reverse the enhancement, so generally I will not color enhance photos until I'm ready to print something.
001 + 087 were pretty much add saturation and darken just a bit.
047 was add saturation and sharpness.
085 added saturation and changed the color opf the sky to blue.
