Colors can be super-saturated with Ektar. Here's a couple of mine. The flower is 35mm Ektar f4 @1/100. The tandem is 120 sunny 16. The 35mm using metered settings does seem saturated, but the 120 @sunny 16 represents accurately the mid-summer grass and 100 degree/85% humidity look of the sky based on the atmospheric density in those conditions.
PS: for some reason the flower didn't upload.
