Colors - Cobalt Blue and Sky Blue

The color of the dress here is "Sky Blue" and the color of the trim is "Pacific".

Which looks a lot to me like the Cobalt blue swatch below.

Dave's dad had proposed instead of blue and green, to think of a dark and light blue.

This dress is from Studio 28 and might not work so well since they are cotton dresses that cost $200.
What do we think?








This is Cobalt blue (a paint swatch). Which would be the color of the darker accents.
I've ordered swatches from the dress places also.








This is the other color I liked from the CocoMyles site but it doesn't really go with the cobalt blue, and it's too light to be the main color (doesn't work for the groomsmen's ties).
This one is Jewel Blue.
