Bettas come in a wide range of colors. The following are just a few basic colorations out there.
Red- Red bettas are one of the classic betta colors. Red bettas can vary to light redish (yellow or redloss) to a deep dark red. When looking for a great red betta, try and avoid black scales on the body. While these bettas make great pets, some breeders consider them as faults.
Blue- Blue bettas are usually either royal blues or Steal colors. Blue bettas are very common, but finding a quality blue betta might be harder. Most blue bettas are petstores are mixed with red coloration. Both red and blue bettas have dominate color traits so when you breed blue bettas, expect some blue in some of the offspring.
Green- Green bettas are alittle more harder to find. Most of them appear to be blueish with green coloration. When looking at a good green betta, watch out for red wash. This is easily spotted by redish coloration usually on the anal fin at the base where the fin meets body.
Yellow- Yellow bettas are becomming harder to find as well. A good true yellow betta should not have black spots. Some yellow bettas have either red or white wash. Most local bettas that are yellow are very dirty with other colors. Still great pets, but for breeding stock, I would suggest looking online.
White-White bettas are rare. Well true white bettas anyway. Most white bettas are dirty. Just like yellow bettas, White bettas often have wash coloration. While many including myself fancy white and red bettas, many breeders consider them faults when trying to breed true white bettas. When it comes to genetics, even when breedng with pure white bettas, most of the babies will have wash coloration.
Black- Black bettas are either melano blacks or black lace. Melanos are considered the superior bettas. Melano blacks should be pure black, with a tinted scale outline. Melanos should have no green tint or red wash. Black lace are more common, They are sort of mutlicolor as they have redish, green, or blue wash. Again they are still great bettas just not considered by many as good breeding stock.
Mulitcolors- Very common, often found in red and blue coloration. They make great pets, and good petstore bettas if that is your goal.
Orange- Orange bettas are somewhat new. Good oranges should be like all colorations, clean and clear of other colorations. Try to look for even coloration from the body to the fins. Often with orange bettas red wash is common, but barely visible. The depth of coloration
Copper- Copper is like steel but copper bettas are really metallic and often have red wash. Good coppers are like an olive colored base with metallic scales.
Clear- Clear bettas are ones with no pigment. While the body is not transparent like a glass catfish, their fins are. The body is a whitish coloration and the fins are clean and clear.
Albinos- Albinos are whitish-to pale yellowish, and have red eyes. Often albinos arent pure white and most of them have red wash on their fins.
Purples- I havent really seen any true purples. Most of them are blue base with alittle red or purple MGs.
Butterflies– This is when the body is one color and the fins have different color. Now what their must be a break in the colorations, thats what set it apart from cambodian. The most common colors are red-white, or blue-white.
Cambodian– This is when the body is one color and the fins are another with no break. Again common color is whitish body with red fins.
Reverse butterflies– When the body is white, and the fins are a different color. They must also have the break like butterflies.
Peibald-Body is a dark color and the fins are clear. Often black body and clear fins.
Marbles– Marble bettas are bettas that are usually two colors but like the name suggest, marbled in appearence.
Pastels– Pastels are usually a clear to whiteish body with light tints of green,blue,grey on the fins.
