Assuming that's a ford color, I want to say it's Bright Island Blue. Considering the very bottom of the truck is a different color along with the center stripe going on, I'm going to say that's a custom paint job. If I'm not mistaken, not exactly a paint expert, but I think Bright Island Blue wasn't available on the Ranger until 2001.
Also, a mod suggestion: 06 Mirrors. I installed a set on mine (brand new, 40 bucks) and the difference is incredible. Not only do you get a larger view but they're also the break-away style, so if someone bumps into your mirror it doesn't knock it off its adjustment, unlike the mirrors you currently have (and I previously had). A supporting mod for those mirrors is a set of blind spot mirrors. I got a set at walmart for four bucks and with some adjusting, it completely eliminates the one blind-spot the Ranger has.
Of course the expo overhead and full length consoles are worthy options as well. Plenty of info can be found on those around the web so I won't bother going into detail here. The how-to sections on here also contain some mods worth considering.
If you have a good budget, a fiberglass powerdome hood is also a very worth while investment. Optionally you can continue swapping parts with an 01-03 header panel swap along with a bumper, or even go newer with the 04 and up look, or mix and match too like I've done. If you're really daring, you can also do an explorer front end clip swap, but you gotta be good at grafting panels and whatnot for that.
Anyway, welcome to the forums and I hope you enjoy your stay here.
