Gray-scale SEM Microscopy Image to Beautiful Color Rendering?

Question

do you know of any Open Source software that could help me perform such a thing: converting a gray-scale image to an eye-catching colorful rendering. I was thinking about ImageMagick (along with EBImage package) or Gimp while resorting to a Script-Fu. Also, being able to automate the process would be great.

I thank you for sharing a fraction of your valuable time in answering my question.

Good day,

You looking for LookUp Tables (LUT). See ImageJ wiki.

Just install ImageJ or it's Fiji distribution, open your image and select Image > Lookup Tables > Choose one nice. If your image is not really grayscale (not one-channel), program raises an exception like LUTs cannot be assigned to RGB images. If so, select Image > Type > 8-bit and apply LUT again.

Use macros or language bindings (I use Jython) for automation.
