Nexrad Color Schemes (discrepancy?)

[texsky]

Tim,

When I try to transfer the radar color scheme I used in older versions of DA such as v2.09, to v3.10a, I notice that the colors, and consequently dbZ values, don't match up. As an example here are a couple of images taken with the same data but with the different DA versions. Is this an issue, or am I missing something here?

I wonder if the newer colors may be a closer/exact implementation, if based on the NOAA radar info page that gives info on coding, product codes, colors, etc. I imagine he had to get the other radar info as well at such a site. Maybe.
My sense is that I like lighter colors so plots can be seen more easily. Here is my palette if you are interested. And, here is a chart made with it, though I am still tweaking the colors (want to make the darkest green a little more dark).

Wally,

I've compared 3.10a against GRLevel3 and the public NWS radar pages looking for dbZ matches, and the colors are better with the older DA versions. So I'm guessing something is amiss with 3.10a, but I can't be certain about that. Hopefully, Tim can clarify when he gets the chance.

Yeah, seems he's churning pretty heavy lately.
Looking closer, I see what you mean.
I'm still "doctoring" my palette (for lighter colors). Will post a new version I'm using shortly.

However Tim chooses to proceed with this, it's not a huge issue for me since the colors can be remapped using Imagemagick. Don't know if others know how to do that though.
