Tomatoes come in every colour under the sun. There are reds, Oranges, pinks, yellows, blacks, browns, purples, whites, greens, bi-colours and striped. Run a search for "heirloom tomatoes" and you will get some good pictures to look at.
The tomato plant itself is green. The fruit of most tomato varieties starts out green in color and matures to some shade of red, or pinkish-red. Some varieties, though, ripen to yellow and some to a deep burgundy color.
pH doesn't have a "color". A given indicator may have a particular color at a particular pH, but what that color is depends on exactly what indicator you're using. Tomato Juice normally has a pH of around 4-4.5, and most "universal" indicators have a color chart you can look at to see what color that range corresponds to.Most wide-range universal indicators (really a mixture of several different indicators) go from red on the acid end to blue on the base end, so I'd expect tomato juice to probably show a yellow or orange color, but you should consult the key for the particular indicator you're using to get the precise hue. This is especially important if you're using a narrow-range indicator, where 4.5 might even be green (this is the case for Hydrion "Brilliant 0.0-6.0" paper, for instance).
The ones that are red contain a chemical called licopene.Licopene gives red colour to tomatoes which is carotenoid. It is like beta and alpha carotene which is present in carrots.
Bob is very red.
When raw, green
When ripe, red.

The reason is because the color of the object's pigment is reflected to our eyes whereas other colors are absorbed.
Black is absorbed! White is reflected. :)
the color pigments are known as chromoplast
Color is actually the color of the light wave that gets reflected from a surface.For example if a car is red, a red color light is reflected from the car and the remaining 6 colors are either absorbed or partially reflected.

I am able to observe the color of tomato juice (red) and the phase of tomato juice (liquid).
The color is reflected by the light to your eyes. That is why you see color.

I think it's mainly the red light that's reflected from the object.
yellow
Chlorophyll reflect green color. That is why they appear in green
Because colors are absorbed the color reflected of is the color we see. For example apples are red every other color is absorbed but red is reflected off the apple.
