That oil is actually 30wt non detergent. Vender for my bulk tank at work uses a honey colored die in it. My 15w40 is a shade darker. And my biodegradable hydraulic oil is almost clear.
Had to quit using him though when I would ship equipment to another branch and they would panic about the color of the oil 
That would explain the work order for my new truck tires! I looked at the sheet as it was being written up, and it said "lavendar torque". Now lavendar is my favorite color...when I asked, the service manager just said we color code the wrenches.That oil is actually 30wt non detergent.

Used to use a bulk vender that put a purple die in there 15w40. Apparently he had a couple customers that had employees that were illiterate and kept mixing up the oils. This way they knew to use the purple oil for the engines
Yup, grey is 100 ft/lbs. The light greenish one is 140 ft/lbs. Not sure what the lavender one is
only got the two I needed for work. They come labeled in NM and ft/lbs. But it is easier just to look for the color you need 
Ok this is an odd one:
Looks like they did 130lbs, Lavender / Purple / Brown.
But factor and spec for her truck calls for 140 ft LBS.
Which would be Aqua or what Daren would call "light greenish one".
I will note: That there seams to be some variances in what colors equals what torque.
