I would look at this way. There are attributes that affect color that also affect taste, but the attributes affecting taste are not limited to those affecting color. An example, brown peppers are brown because the green chlorophyll present in the pod does not degrade when the pod ripens due to the mutation
cl. When the pod would otherwise be red, the remaining green chlorophyll causes it to color brown. So, the taste of all brown peppers is influenced by the presence of chlorophyll. Another example would be the color mutation "
c2," which acts to reduce the levels of carotenoids produced in the ripe fruit generating (in the absence of other aberrant alleles) an orange mature pepper. Because carotenoids are precursors to many of the chemicals responsible for the flavor of pods, a reduction in the level of carotenoids from what would otherwise be a red pepper would have an impact on the flavor of the pod. Different mutations, such as
c1 +
c2, a pale yellow mature pod, would cause a much greater reduction in carotenoids therefore have a similarly greater impact on the flavor of the fruit. But these attributes affecting color aren't the only ones affecting taste. For example, the brix/sugar content of the pod governs the perceived sweetness, but doesn't affect color. And, as many people have mentioned above, different peppers have different flavor profiles, despite showing the same color.
Nice one, Bhuter. I remember hearing that and finding it interesting, too. We may each look at a lawn and think "the grass is green," and we'd agree that it's green, even if I were seeing the color you would describe as orange - after all, everyone's always told me that color is "green." And if I use the label "green" for everything I see as orange, and you see everything I see as orange as green, we may be seeing different colors, but we have no way of ever knowing whether we do or not. It's an interesting thought experiment at the least - or MF, if you prefer
