    If Part A of the RA-4 Chemistry turns a horrible brown (and is therefore expired) but Parts B and C are still clear are parts B and C still useable or should I throw them out as well.

    Thanks,

    If any component solution (could be "A'" ... more commonly it is "B" in the Photocolor or Trebla kits) turns dark -- I've had them nearly solidified - it is *SHOT*.
    The remaining solutions are probably OK ... but unless each component is available separately they are of no use- and even if they were, the inventory maintenence quickly becomes a horror show.

    I might suggest the JOBO - TETENAL RA-4 kit - two (2) component color developer (one is in a GLASS!! bottle). In my experience this has an *excellent* shelf life with opened bottles, especially replacing the air with JOBO "Protectan" spray.
