Thoughts - Which Color Scheme Works Best for EVS Maps?

I spent today digitizing the King George Islands located in the Tuamotu Islands FP. The top atoll, Takapoto, was just completed using my new NIMA color scheme. Not only am I limiting layers to EVS island projects to island polygon, reef shallow, lagoon and island water feature, but I've changed my color scheme to match NIMA's nautical charts. My current color scheme is as follows:

island polygon is R-245 G-245 B245

reef shallow polygon is R-205 G-225 B-235

lagoon is R-225 G-250 B-255.

Takaroa Atoll, completed a few months ago, contains my old color scheme:

island polygon is R-240 G-232 B-217

reef awash is R-208 G-234 B-224

reef shallow is R-153 G-214 B-236

lagoon is R-090 G-169 B-211

In both projects the vegetation layer R-157 G-179 B-151 and the deep ocean layer R-165 G-207 B-231 are unchanged.

For visual appeal, I like the old style. The NIMA nautical chart style gives a cleaner, crisper look. What do you think?

Enjoy!
