this is a total shot in the dark, but by your description and the picture posted above. I'd guess you have a P. metallica. By your description of the "brilliant cobalt blue coloring. the rufilata in the pics shows a lot more yellow than blue. so if you do have a metallica you have one of the rarest and most coveted species in the hobby, if not then you probibaly have a P. rufilata like you said.
You can adjust your monitor colors by right clicking on the desktop and selecting properties. in one of the tabs of the window that pops up you will see some color options. if your color is really messed up you might have a loose monitor cable or a bent pin on your monitor cable, try to jiggle the cabel where it attaches at the back of your computer and see if your monitor's color changes, if it does then the cable is loose or has a bent pin. in case you dont know what the monitor cable looks like look on the back of the computer tower, it is likely the biggest and widest cable attached at the back, unless you have an old printer then it is the second largest. Old printer cables are huge anbd wide also.
