This picture shows the two colors side by side nicely. Although take into account the different fabrics as the gym bag has a slight sheen being nylon. Angel is quite a bit darker in tone and Cool is much more subdued with a slight green. I saw these together in the CRB tanks. The Cool reminds me of Miami Vice for some reason. I like the two blues paired together with a third contrasting color (electric orange Tang Light Flow y). I was a bit worried that the two blues were too close in tone to be able to be put together but there far enough apart that you can pull it off.
