I hear you. Photo processing is not one of my strengths. The 650 is a dark? red, the roadster is bright red and the S is orange or I have always said 'salmon'. Well, because dog are ah, oh, ah 'pink' and the S looks orange like some of the fish I see at the market.
Red drives me crazy in photos. My phone handles it better than my two cameras. Of course that is with me at the controls.
