The perception of colors is purely subjective. The brain perceives them in relationship to their surrounding colors and the "temperature" of the incident light. Color films, particularly reversal ones like slides, record an absolute value of color based on the incident light temperature. This is why daylight balanced films have an orange cast when used under tungsten illumination, and daylight balanced films look blue when used in daylight conditions. The same is true of the various temperatures of fluorescent illumination (daylight, cool white, warm white, etc.) There are compensating filters available.

Unlike with musical tones, there is no perfect pitch for colors, which means that whatever you recall in your mind's eye regarding a particular color on some object won't be precisely the same hue and tint as what it really was. This is why photography uses that 18% gray card as a standard and the impetus for the development of things like the Munsel color system.

Some people like saturated colors, while others like softer, more pastel colors. To each his own.

I'm very impressed with what photoshop did with the dense areas of your pic.
