How the heck did you make that nammy blue? LOL! I know some gals that can make something of mine the same color :naughty:

Below is a picture and a quote from this site:
http://www.geocities.com/CapeCanaver...radios/tv.html
"Back in the days when the NTSC color TV system was being developed, a test color transmission of some fruit was done. Some practical joker took the bananas and painted them blue. In the NTSC color system, the color (more precisely chroma) is encoded onto a subcarrier, the phase indicating which color. Yellow 180o out of phase yields blue. The guy at the receiving test site would adjust the phase (commonly called "tint") to get the bananas right, but then the rest of the fruit would be wrong! "

RCA established a laboratory in Astoria, Long Island, three miles from the
transmitter at the Empire State Building, where companies could bring
receivers for testing. One night in April, 1953 the RCA Princeton labs were
conducting critical tests with test patterns, while receiver engineers asked
repeatedly for live pictures. When the transmitter became available about
12:30 a.m., the engineers requested that live talent and some fruit be
televised. George Brown of RCA noticed a can of blue paint nearby, and
hastily painted the bananas blue. The receiver engineers spent a half hour
unsuccessfully trying to get all the colors correct.[1] An apocryphal story
tells of one manufacturer's crew (Zenith) at Astoria who were so certain of their
receiver design that they turned off the set, said "They have the phase
wrong!", and went to a late dinner while waiting for the studio to correct
their error.

WTF is Gimp?

GNU Image Manipulation Program. It's a wonderful and very powerful graphics editing program, and it's open source too. Thouse of us that use Linux are familliar with it, think of it as almost and open source Photoshop. The GIMP runs in, and can be compiled for, most variants of UNIX, and I belive it even runs on Windows too. I don't use Windows so I haven't used that port of it though.
