the gold honey dwarf gouramis arent true dwarf gouramis... they are honey gouramis.. . an entirly different species.
you could breed a powder blue with a sunset (the true red form) but that would give you the natural color, since those two forms are just the narural form without either the red or blue.
i wouldnt even try, unless you have the space, time, and patientce. dwarf gourami fry are incredibly tiny and they can be quite diffifcult to raise because their mouths are so tiny. you would need at least a 10 gallon for a pair, and then a 20 gallon for the fry, for there can be 200-600, depending how many eggs hatch. then you are going to need an even bigger tank, at least 50 gallons, depending on how many sirvive. then you need to separate the males and females during the move, to keep them from inbreeding. since it is likely that there will be many males, you wont have to separate them.
with all of this work, if you still want to breed them and go through all of they work, you might as well get a breeders license so you can sell them to you LFS, otherwise, i hope you like dwarf gouramis, cuz you're going to have alot of them
