Blue is for Exploration and White is for special. I haven't gotten any of the Special ones yet though, so no idea what they do. Though they do list all of the possible recipes in the stats. --- Ah, yes, the Negotiator: General Kenobi <sneaky beeping>
Maybe after some more story missions, im having too much fun shoot pirates in the head with arrows and knifing crabs on the beaches instead of doing the main story. --- All hail the mighty woolay. http://i1115.photobucket.com/albums/k541/Muddywater10/stupid3-23.png
Blue is specifically for holding your breath for a long time - essential for some relics - and swimming faster, while white contributes to 'special' syringes, notable among which is 'Touch of Death' which makes every enemy die to a single bullet and 'Untouchable' which makes you invincible. --- "I love finding threads like these, it's like walking outside and finding the city's been bombed while you were sleeping." - Blighboy
The Special recipes are both late game. You won't run into those for quite a while. The blue start showing up not too far in though. --- Reading is good. It improves your vocabulary, expands your imagination and provides endless amounts of information.
