Keep in mind – it is hard for us, developers and pro-users to write documentation as we know chunks of GRASS too well. Māris, This was all on me, not the manual page. I was in a hurry and didn't experiment. If I could think of technical improvements to the r.colors page I'd offer them; currently I can't think of anything. My only request for the docs, which I've expressed before, is to change the module names' color on the index page from pale green on white to a darker green. Older eyeballs, with many miles on them, do much better with high contrast between foreground text and background color. It's no different from slide presentations: the greater the contrast the easier the text is to read.

Your data looks continuous, so what do you mean by "slices" ? A continuous color table doesn't have slices. The data are continous. What I meant by 'slices' is smaller ranges between colors so finer depth increments can be seen.

[GRASS-user] What color style for bathymetric raster map?
I've a raster bathymetric map (attached) to which I've applied r.color = 'elevation' because I didn't see another style more appropriate for aquatic environments. I'm sure there is at least one in various shades of blue and I'd like suggestions for what to use or do to create one. Also, is there a way to get narrower depth slices since the riverbed is comparatively shallow and flat in this data set. BTW, I sent a request to the appropriate data source for the name of the most appropriate terrestrial LiDAR data set for the north side of this river.
