Completely off-topic, but I know some forum users are experts in color...
I'm designing a medical software and it needs to display some temperature measurements in 2d. The doctor needs to see small variations in temperature in order to detect problems.
So my task is to design a heatmap that gives the maximum amount of detail and resolution to a human... This is crucial. It is not about a mathematically rich heatmap for a computer(I could use a 32 bit grayscale for this).
So I have 2 points for lower and higher temperatures, I'm going to assign a color to each one.... but then, the interpolation between the two needs to be very rich.
Of course I'm also implementing some filters and tools for the doctor to better discriminate data. But I'm still wondirng...
What is the best approach for a human readable heatmap ? change HUE? HUE + Brightness? some other color space ?
Thanks!
