However Pentax dSLRs have a reputation that their default "Bright" setting is somewhat over-saturated and if my K100D is any indication there is a tendency to toward a sunny/yellow cast - this sounds almost "ideal" for your usage - and explains why you are happy with the color balance of your *ist.
dpReview on the K200D page 19 has a Macbeth chart where one can compare with other settings and other dSLRs - they said -
"
The K200D's color response was very similar to that of previous Pentax digital SLR's. The image output in the default 'Bright' image tone is quite highly saturated (vivid), as can also be seen earlier in this review. Switching to the Natural tone calms color saturation to more typical levels (compared to other digital SLRs). "
This was similar to
dpReview take on K100D where they said:
"
The K100D's color response was quite similar to that of previous Pentax digital SLR's, that is quite highly saturated (vivid) in the default 'Bright' image tone, as can also be seen earlier in this review, it can lead to color clipping in certain situations (such as red flowers in direct sunlight). Switching to the Natural tone calms color saturation to more typical levels (compared to other digital SLRs). "
Some direct comparisons of my K100D -
K100D - Landscape Mode (close to Bright)
K100D Natural setting
Canon PowerShot S80 (p&s) Landscape mode -
