SPN tutorial - Enhanced colours
NO SELECTIVE COLOUR! (for once!)
Made in PS CS3 but is probably translatable.
Take your base and prep it, but it is very important that you merga all your screen layers or whatnot into one single background layer before starting step 1.

//Step 1

//Step 2

RED: 17, 1,00, 225
BLUE: 0, 0.95, 240
//Step 3
Duplicate base ontop and set to luminosity
//Step 4

GREEN: +34
//Step 5
New colour balance layer

//Step 6

Highlights: +53, 0, -20
//Step 7
