How do Red Green and Blue Screens make yellow in RGB Technology?
I recently saw the commercial where Sharp announces it has added yellow to the standard RGB configuration that standard TV screens use to make up colors. How is it that Red, Green and Blue make yellow on these TVs?
Answer:
The visual light color wheel is not the same as what we are taught in art class as the standard color wheel. When you mix all the colors of light together, you get white, as opposed to mixing all the colors of paint together and getting black.
So, when you mix blue light and green light, you get yellow light. The more light you add, the brighter it becomes. I know this isn't a very scientific answer, but it's the way I understand it.

Blue Topaz Engagement Ring
People might think that wearing engagement rings, with or without any gemstones, is very old tradition. But in reality it is not true. Though the practice of wearing engagement rings started from many hundred years ago, it is still quite fresh and novel. At present, we can see new trend in the jewelry business which don't include much diamond engagement rings. The place of diamond has taken by other precious gemstones such as sapphires, emeralds, rubies, pearls, and also blue topaz. It is possible to mix blue topaz with either gold or silver. But it is obvious that one chooses gold for engagement ring. Gold is the most spiritual and noble metal needed for your engagement ring.
Talking about the hardness of blue topaz, it ranks 8 at Mohs' scale. So, we can say that it is a durable gem. Topaz comes with different beautiful looking shapes and sizes. Regarding the color, it comes in blue, yellow, white and many other colors. Among them blue topaz is the wonderful gem which are found from dark blue to lighter blue hues. Naturally mined blue topaz is very rare and uncommon. Topazes that are found in the markets today are mostly artificial. They are produced in the laboratory through the process of irradiation over white topaz. The increasing demand of blue topaz has also increased the price of white topaz.
Though it is a tough stone, it may still break if it is dropped. Cleaning and maintaining topaz engagement ring is not so difficult. You can take it to local jeweler to clean it or you can also do it on your own at home.
The meaning of engagement rings is quite clear. They are the symbol of token of love and eternal commitment of two persons. On the other hand, blue topaz gold ring is the best ring that promotes personal growth and leadership. It also gives you a feeling of belonging to your surroundings and nature.
