Important: One thing to note up front here is that not all images actually have any areas in them that are supposed to be neutral gray, and obviously, you can't find what's not there, so if that's the case with your photo, no technique for finding midtone gray will work.
Unfortunately this colour is much more true to blue than green. I now have a soft turquoise but washed the colour out after only 10 minutes. So I'll be surprised if it lasts for more than 2 weeks. Overall I think the Joico colour has great pigment but don't go with the colours you see on the package!!
Increased Responsiveness. 1  In JOC, work can start between 75-85% faster than traditional contracting methods. Since the contractor is already under contract and on-call, you avoid the entire traditional procurement time. Studies have shown that for small projects (less than $20,000) the average procurement time using the traditional system was as much as 233 days compared to 42 days for JOC, for a savings of 82%.
