Increased the contrast of the initial BLPs, therefore causing the primary dirt to look red-ish. No red/green color-combo intended.
Edit: 'Learning' color-combinations? What? Lol sorry but last time i checked that was based on opinion, not knowledge. Regardless of the fact that i do see an unbalance of contrast in my pics. It's got nothing to do with learning; it's a matter of likes and dislikes.
