Don't stress yourself about the colour of the stocks. Just get matching colour and grain (if possible) and then sweat, strip, sand, stain to your desired colour, then finish with tung oil or linseed (or whatever you like). Personally I'd go with darker wood and the red would be deeper. Of course you can do a lot of things if you are handy with stains.
Getting mismatched wood and trying to stain it to match is not easy. Been there, done that. A lot of trial and error. For $25 more I'd get the close matched set.
Don't be afraid of a beat up set too, I got a POS set on Ebay and I refinished it, thought it looked cool as hell. If you plan on shooting your rifle, your beautiful wood will get messed up eventually.
If you get nice matching wood with good figure, you just want to oil it and keep it as it is. Oil finish looks awesome on a Czech rifle. All I did on this VZ24 is sweat out the cosmo and use Linseed oil.
If you get bland wood with little figure, you might just want to use a lacquer.
Just be careful with those UHG, they can be fragile when removing. I broke a couple in my day. Crazy glued one back together
