The original image would help.
Question for you: is Ruby Grapefruit a red fruit? How about Blood Orange? Is peach a red fruit (at least some varieties?).
Darn it looks like this phone interface does not allow me to upload pictures, or I would attach a picture of some of the apples that grow on my tree for a decision as to whether they are red fruit or not.
By the way, are you aware that in the United States, tomato is legally classified as a vegetable and specifically not as a fruit? This had to do with a tax ruling because at the time fruit was subject to a tax that vegetables were not subject to.

See my demo: https://www.mathworks.com/matlabcentral/fileexchange/26420-simplecolordetection Or use the Color Thresholder app on the Apps tab of the tool ribbon.

Imran Y: Okay, go ahead and write the code you need.
I would, however, recommend to you that you first figure out how to know when a tomato is sufficiently ripe for your desired purpose, taking into account all of the different varieties of tomatoes that you will be dealing with.
it might not turn out to be strictly necessary to measure Ethylene emissions but read that link anyhow because it is relevant.
