Can i have a lut for 256 colors

dksamuel
Respected Imagej researchers, Is it possible to have 256 colors (as
opposed to shades) in a lut. I would use such  lut in my scanning
electron microscope images, thanks

Hi Duleep,

The Image>Lookup Tables> has many examples of 256 color LUTs.
You can also create your own by editing an existing LUT with Image>Color>
Edit LUT...
Or import a text-based existing LUT with File>Import LUT... . The LUT file
should be tab separated and have this kind of content:

Index Red Green Blue
0 255 0 0
1 254 10 254
2 253 20 253
3 252 30 252
4 251 20 251
5 250 10 250
6 249 0 249
...
255 248 248 248


Sincerely,

Jerome.

Hi Duleep,

Check oit the Glasbey LUT, which is included with Fiji.

Hi Duleep,

When you convert an RGB image into 8-bit color, you actually convert the
image to a 256 color lut.  The order is somewhat confusing, but it will
certainly give you a set of values.  You could then save that lut as a
file, of the sort that Jerome suggested, and sort the values to your
heart's content.
