The RGB color model is an additive color model in which red, green, and blue light is added together in various ways to reproduce a broad array of colors. The name of the model comes from the initials of the three additive primary colors, red, green, and blue.
The main purpose of the RGB color model is for the sensing, representation, and display of images in electronic systems, such as televisions and computers, though it has also been used in conventional photography. Before the electronic age, the RGB color model already had a solid theory behind it, based in human perception of colors.
RGB is a device-dependent color model: different devices detect or reproduce a given RGB value differently, since the color elements (such as phosphors or dyes) and their response to the individual R, G, and B levels vary from manufacturer to manufacturer, or even in the same device over time. Thus an RGB value does not define the same color across devices without some kind of color management.
Typical RGB input devices are color TV and video cameras, image scanners, and digital cameras. Typical RGB output devices are TV sets of various technologies (CRT, LCD, plasma, etc.), computer and mobile phone displays, video projectors, multicolor LED displays, and large screens such as JumboTron, etc. Color printers, on the other hand, are not RGB devices, but subtractive color devices (typically CMYK color model).
What made you think that I'm in love with you? One hundred ways to be apart from you
What made you think that I'm in love with you? One hundred ways to live my life It's true, it's absolutely true
What made you think that I'm in love with you? One hundred ways to heal my heart, undo
You painted all in grey And I'll be running out Red, green, blue it's true They make my life full of light flashing, now There's no dance in the dark Let the fireworks start
Running to the stars Never gets you very far Follow me and then We'll go round and round again
When you wait too long Just carry on Believing you're wrong
If the world explodes right now I will hide you deep underground Leave you on the top of the biggest tree From there you can see the blue sea
There's no dance in the dark Let the fireworks start
Running to the stars Never gets you very far Follow me and then We'll go round and round again
When you wait too long Just carry on 'Cause you're not alone Believing you're wrong
