The standard way to preserve specimens and colour is to go through the tedium of transferring them through Kaiserling's solutions (1 to 3).
I presume books still have the method, but if not, e-mail me privately and I will get the method typed out for you.

Subject: whole organ fixation with color retention


Hi everyone,

We have a researcher interested in retaining whole organs for teaching 
purposes, but would like the original color of the organ to remain intact.  
I know a similar topic was addressed not too long ago, and I have read the 
archives, but wanted to see if anyone had suggestions other than 
plastination.   Ideally, he would like a fixative - and the only one I've 
found a reference for contains chloral hydrate - which he can't purchase as 
a DEA number is required to do so.

Any suggestions you may have would be greatly appreciated.

Thank you,
Louri
