On the contrary, what you said was that you "found that vga has a much more vibrant and better color".

Think of it like this. With DVI the computer tells the monitor "see that pixel there? I want it coloured like SO... and the next one SO, and the one after that SO" and on for the rest of the screen. Using VGA the computer says to the monitor "take a deep breath, start at the beginning of the line and every 14.628 micromillinanoseconds I want you to throw a blob of colour into whatever pixel's nearest until you get to the end of the line with the colour depending on how loud I'm singing at that moment", and then it trills for a while. It gets the job done but it's rather approximate. They did it like that in the old days because they didn't have enough bandwidth to do it properly. If you go back far enough a pre-VGA protocol just told the monitor "and then draw me a light blue 'h' and then draw me a light pink 'o' and then draw me a deep red 'g'...".

Before that colour was dependent on the monitor, you could choose amber or green.

DVI is better than VGA for TFTs because they are digital and VGA is analog. A TFT displays its picture digitally, pixel per pixel. Via DVI the panel gets data for each pixel, so the picture generated in the graphics card will match exact with the pixels on the panel itself.

Not so with VGA. First, the picture is generated digitally in the graphics card. Then it's converted to analog. In the TFT they will be converted again to digital (=> senseless twice conversion => quality loss), using the phase and the clock, and it'll be calculated which pixel should display what color. As the phase and clock can't be adjusted so precisely that a pixel of a picture generated by the graphics card will be displayed by the appropriate pixel on the panel. Means that the picture will be interpolated a little bit, which again means quality loss.

The electron cannons of the CRT need analog signals, that's why VGA is the best for CRTs and DVI would make no sense here.
For TFTs, DVI is the best. I won't get a TFT with no DVI.
