Corner experiments

Since I don't have a one-for-one match for all of the threads originally used on My Way, I need to play with my threads and colors for each area. (Tough job, but somebody's got to do it.) Before I start stitching either the corner or center of a block, I go through my threads and select replacements for the called-for threads in that area. Rather than just assuming I'll always use thread X in place of original thread Y, I like to see how all the pulled threads work together.

Sometimes it works. Sometimes it doesn't. Case in point - the original threads I pulled for the corners on my block G:

Wow. That outer teal band, while pretty by itself (especially stitched in two strands of Impressions), sticks out like a sore thumb next to the rest of the corner. It's a bit too bright and provides too much contrast. The problem is that the instructions say to pull a dark color of this family, and I really don't have a dark teal.

I wondered what would happen if I changed that band to a dark gray-blue from my neutrals family. Here's the result:

It's a bit tough to see in the photo with the reflection off of the pearl cotton, but this combination seems to be better, though I'm still not completely sold on it.  What do you think?  Should I change something else?
