The color that is on the car now looks like what they called Mahogany used in 76 and maybe 75.
It was a hot seller when dressed up with some painted on striping.
A Friend of mine bought a new one in 76 that color and we painted silver strips and the L-82 on the hood with 735 Mercedes silver and did some other striping around the fender vents and quarters.
That was one of the best looking vettes I have ever seen and like you I was not crazy about the color when he first got the car.
The original color Brown and that year would not be worth the effort to change back to that color.
To make money on that year and combo you will need a Fancy paint job of whatever color you chose and a little beefing of the engine.
