Because tomatoes have special pigment, and nutrients which is red in color. And leaves are green due to the cholrophyll pigment present in them . Hope it hepls..
This of course begs the question “Why are tomatoes red and lettuce green?”
One article argued that these object properties will change the wavelength distribution and the perceived color of that object – and as you can see in Figure 3 – that’s why tomatoes are red and lettuce is green. I don’t really know exactly why the tomato is red – i., and e. Why it only reflects the reddish part of the light.
Why are the leaves of a tomato plant green?
The green color of the leaves is due to the pigment, chlorophyll , which is essential in photosynthesis. Leaves help in preparing food for the plant. Red colour in tomato fruits is due to the pigment, lycopene.
Why tomatoes are red?
Lycopene is the compound that gives tomatoes their signature red color . You can also find it in other fruits and vegetables, such as carrots or watermelons. When the tomato is ripe, the chlorophyll is degraded, and the red lycopene color dominates.
The colour red of a tomato is caused by mostly one molecule: lycopene. They contain different molecules, simply because it’s these molecules that change the colour. Some claim yellow tomatoes are sweeter , but it will strongly depend which yellow tomato you’re comparing to which red tomato..
One of the next things we wondered was; what is the red colour of tomato?
Red colour of tomato is due As the tomato ripens , its colour starts to change from green to yellow and then eventually to red. This is due to the breakdown of chlorophyll, which in turn synthesizes a red carotenoid (another pigment group), lycopene. When ripe, the carotenoid can easily be seen as the dominant colour of the tomato, i., and e; red.
One way how to turn green tomatoes red is to ripen mature green tomatoes in a well-ventilated area at room temperature, checking their progress every few days and discarding unsuitable or soft ones. The cooler the temperature, the longer the ripening process will take.
When conditions brightened, however, the plant winnowed down its genes, keeping the ones that made its fruit red. It also ditched genes that produced toxins-a fact which sets it apart from the inedible fruit of another member of the deadly nightshade family, the potato. (The edible part of a potato is the root, not the fruit.).
Why do tomatoes turn red when ripe?
This is due to the breakdown of chlorophyll, which in turn synthesises a red carotenoid (another pigment group), lycopene. When ripe, the carotenoid can easily be seen as the dominant colour of the tomato, ie red.

The answer is that yellow tomatoes in a green house as well as green (unripe) tomatoes that still have to turn yellow. What makes a tomato yellow? Yellow tomatoes on the other hand have a very different concentration of these colour molecules. They contain far less lycopene and β-carotene than the red variety.
What makes tomatoes different colors?
Tomatoes contain several colored compounds, with the dominant ones being the green chlorophyll and the red lycopene. As the tomato ripens, the chlorophyll is degraded and the red color of the lycopene dominates.
Tomatoes contain two pigments for photosynthesis chlorophyll, which is green, and lycopene, which is red.
