Bottom line
Per 100 g, Grapes (Green) provides 80 kcal, 0.9 g protein and 18.6 g carbohydrate; Grapes (Red) provides 86 kcal, 0.9 g protein and 20.2 g carbohydrate.
That is a difference of 6 kcal per 100 g.
Red grapes carry slightly more sugar and with it the anthocyanins that give the skin its colour; green grapes are a touch lighter and sharper. Both are easy to eat far past a portion — a cup is about 150 g, and it goes quickly.
In short: green grapes is the lighter option per 100 g, but with fruit the portion on the plate usually matters more than the difference between them.
