Oh I know but this is actually fun. Moving my antenna 30 ft. brought in local channel 2 and after a meeting with Tektronix yesterday I learned from their engineer Steven Holmes he's seen 5 feet make all the difference in antenna placement.
Now today I learned at the paint shop that adding black paint to white paint actually makes it go blue. I didn't know that and am applying video additive color approaches to the subtractive color of print, or in this case paint.
I was able to borrow a Porta Pak Chip chart and used the 6th chip from the top left, which is one chip to the right of middle, to sample for color mix. The result included a bit of Yellow and Red oxide for the 40%ish chip. A darker chip two to the left was similar but it had Yellow oxide and regular Red in it's mixture. It appears that paint color science differs from the video world. They couldn't convince me that adding black paint to white paint went blue at first but then I had to consider they are paint professionals in north Hollywood and work with the studios a lot.
I'd love to learn more about the print vs. video color approaches especially how black drops in white go blue. Anybody got some experience with that?

I've learned from Terry that it's best to start with white paint and add drops of black to achieve the proper shade. Apparently most grey paint premixed has some blue in it. My contractor looked at my samples and said to put the desired color on a piece of cardboard and they could computer match it. It got me thinking that it would be better to get a real chip chart, that I assume has 40% or close to it section and use that for the computer match. I asked if the matching would result in a mixture of black and white paint and not some other tints/pigments and was told yes. Is anybody familiar with the new breed of paint computer matching and if it can be specified to make the color with only white and black pigment? I know I'm not working for NASA but I would like to make an educated stab at getting close. Any other suggestions are appreciated.
