No. A stars color is determined by the heat it produces. Like a peice of metal when heating up will got from red to yellow to white (red being cooler the white) a star color is determined by its color. to get a better example of this see this chart which shows star temperature in Kelven.
Stars can be classified by their surface temperatures as determined from Wien's Displacement Law, but this poses practical difficulties for distant stars. Spectral characteristics offer a way to classify stars which gives information about temperature in a different way - particular absorption lines can be observed only for a certain range of temperatures because only in that range are the involved atomic energy levels populated. The standard classes are:
Temperature
O 30,000 - 60,000 K Blue stars
B 10,000 - 30,000 K Blue-white stars
A 7,500 - 10,000 K White stars
F 6,000 - 7,500 K Yellow-white stars
G 5,000 - 6,000 K Yellow stars (like the Sun)
K 3,500 - 5,000K Yellow-orange stars
M < 3,500 K Red stars
The fact is that starts just don't get that hot. Btw indigo would be before violet in the color spectram and I don't believe any stars of that color exist either.
The cool weather is the factor that caused the leaves turned into purple color of some st.paulia species.
Mites, thrips if you get a bad infestation. My cats have been known to take a bite once in awhile.
Violets need to have partial sunlight and minimal water. They also need to stay out of the cold weather. If these guidelines are met, violets can last forever.
Artificial lighting is excellent. Use shop lights from hardware store, the inexpensive type. Purchase the fixture 48in long. Use bulbs, one cool and one warm type. Place six to eight inches above plants, this can be accomplished by attaching fixtures under a shelf. They do make the adjustable wire types from a hardware store. Also, rubbermade types. Leave lights on 8 to 10 hours a day. Consider these will give off some heat.
This is dependent on how many African Violet plants you are growing and their stage of growth. African violets should be fertilized during their flowering period. Mine flower in the late fall through to spring. After they stop flowering, I continue to water them once a week, but leave out the fertilizer. Growing 4 plants in my home, I have used one 10 ounce bottle of African Violet fertilizer in one year's time.
Growing African violets for a hobby is a lot of fun. You can even join the African violet association www.avsa join a club near you and start showing your African violets, it's very rewarding. Also, this is a wonderful hobby for children.
Yes, soap can leave spots on the leaves and may burn them. If you are using it in hopes to kill insects, it's best to use pure neem oil.
You can create humidity around your violets by placing pebbles in the plants saucers and sitting plants on top, keep filled with water to just enough so that plant pots are not sitting in the water. You don't want your plant to become water logged and rot. Another way is by sitting containers filled with water around your violets. Also, you could place a humidifier in the room.
Yes, please look at the related link from another similar question. You separate them the same way.
Yes but you would have shop around and place the order early.
African violets are not poisonous to pets if they eat a little but not a daily diet. Warning; Cats love to eat African violets, maybe give your cat some cat grass so it will possibly leave your violets alone.
There are some Russian Hybridizers that have raised very large varieties of African violets within the last five or so years. Please see the related link.
The best light is either fluorescent light or natural indirect light, not direct sunlight or your plants will receive burn marks. Keep plants moist, let dry out a tiny bit then water them again.
