Knitter's Dilemma

It's a gray, rainy morning . . . perfect for knitting and drinking coffee.  I'll warn you.  It's not perfect day for taking pictures. 

I'm trying to make sense of a swatch I knit last night, and I thought the light of day would help me make a decision. 

Here's a knitter's dilemma.  I tried two different needle sizes on this swatch, and I can't decide which one to use.  One of these will have to do, but what I'd really like is a needle size in-between the two.

I found this week's color inspiration on a recent museum visit.

High contrast and striking details.
