Autumn Magic Question

I spent most of last week working on Autumn Magic.  I have really enjoyed working on this and this week was no exception.  This in spite of the fact that I am stitching background trees that are really just blobs of orange, yellow, and green.  This is what that page looked like at the end of the week:

However, I have been stymied by a question that came up while I was browsing through the Heaven and Earth website at the end of the week:  What is the difference between a regular chart and a chart with max colors?  Does the result justify the extra work of stitching a chart with increased confetti?

There are now two versions of Autumn Magic: a regular version and a max color version.  The only difference that I can see in the mock-ups between the two versions is that the max color version is lighter.  I like the lighter version because I think that the chart that I am stitching is eager to choose black when the colors get darker.  Logic would indicate that more colors would increase the amount of confetti in the piece and that it should increase the detail as well.  However, I wonder if there is some kind of law of diminishing returns when it comes to the number of colors in the chart.

Has anyone had experience with this?  Have you ever compared the two versions and determined which is the best?

I suspect that in order to find the answer to my question I am going to have to stitch at least a page of the max color version so that I can see the difference.  Based on the results of that experiment I will probably decide whether or not I want to switch versions. However I can’t do this experiment right now and I don’t want to spend time working on this project if there is a possibility that I will be changing to the max color version.  So for now I am putting this project on hold.
