Changing the hue of an image

Linda Barthel-2
I have an 8 bit grayscale image, .tif.  Want to change it to a color image,
with a "grayish" blue hue.  Very easy to convert to straight blue-but that
isn't the best color.
Thanks,
L

Re: Changing the hue of an image

Hej Linda,

This should be quite simple

Start with an image
Then
Image/color/edit LUT
A window appears that allows you to edit the  a LUT
With the mouse select the top left square and end with the bottom right square

The software asks you for the RGB combination for the top left square (lowest value)
Maybe 0,0,0               which be  black
Then the combination for the last (most intense) square
Maybe 128,128,255
Blue set to 255 and R & G to 128, a blue plus grey -
All the intermediate values are interpolated.

Save the new LUT in Imagej's   LUTS folder and restart.
The LUT will now be available.

Dear Linda

Maybe the Cyan LUT is working for you (Image > Lookup Tables> Cyan). Or you can take any LUT, select Image > Color >Edit LUT... and select all the fields in the Editor. It will then ask you the start values for Red, Green and Blue and after 'OK' for the end Values for Green, Red and Blue and then fill in the gradient for the LUT automatically, so you can create any LUT to your own taste.

Best wishes

Thanks Jeremy-worked perfectly.  I used 115-red, 175-green, 255-blue to get
the desired hue.
Regards,
Linda
