I just downloaded LR 3.6 to a new computer running Win8. The colors in LR are yellow other pro. ok why would it be doing this. How can I correct it? Is it win8 or LR?
Likely the screen needs to be calibrated.Your other programs are not color managed, so they don't observe they won't respond to your current display settings the way Lightroom will, which is expected. However, with color management, the point is to get as accurate color as possible, but if it is set up incorrectly it will display color incorrectly.
Best entry level: Spyder 4 express
Best overall: X-rite i 1 Display Pro
Best upgrade option: Spyder 4 express > Color Eyes Display Pro (use existing sensor)
Most high-end monitors (Eizo, NEC) have their own bundled/integrated calibrating solutions.
