Colors in our life
Color affects how we feel in a way. Millions and millions of colors can be perceived from our eyes. For example, sky blue, vibrant blossoms, lush green forests, and all kinds of beautiful colors somehow increase our attention, give us inspiration, and the ability to connect with other people.
“True color”-color accuracy
The "true color" we usually talk about is the color accuracy representation based on the original image of the real world. When it comes to color accuracy, we know it’s very important for photographers, designers, and other Imaging pros. Color accuracy is an important feature when we refer to the cinematic experience. We guess many people could recognize the colors of different species of fish from the movie Finding Nemo. So not just pros, we need to be aware of the importance of color accuracy when we choose a display device.
Color space and color gamut
A color space is a specific organization of colors. In combination with color profiling supported by various physical devices, it supports reproducible representations of color -- whether such representation entails an analog or a digital representation.
So how to describe a range of colors within the spectrum of colors or a color space, that can be reproduced on an output device? That's what we are going to talk about: color gamut.
Rec.709, DCI-P3, and Rec.2020 are the three main color gamut standards used for current projectors on the market.
Rec.709 is a standard developed by ITU-R for image encoding and signal characteristics of high-definition television with the most recent version released in 2015.
DCI-P3 is a color standard defined by the Digital Cinema Initiatives (DCI) organization in 2010, a variant developed by Apple Inc. for wide-gamut displays.
Rec.2020
In Hollywood films, Rec.709 and DCI-P3 are the standards for cinema-quality colors. So what is Rec.2020? ITU-R Recommendation BT.2020, more commonly known by the abbreviations Rec. 2020 or BT.2020. Rec 2020 is a wider color gamut than Rec 709 and DCI-P3, which is the current industry standard for HD. Rec 2020 promises more brilliant images, though only new display technology is able to show these.
Check out the CIE 1931 Chromaticity Diagram below to understand what is a wider color gamut.
Three primary laser projectors- wide color gamut and accurate color
The laser light is usually very pure in wavelength so it has the property of monochromaticity. All the colors that our human eyes perceive can be modulated by the red, green, and blue lights. The ideal system for a laser projector utilizes three primary-colored lasers. The laser light from true RGB models is diffused, three primary lasers are then irradiated on the DMD chip respectively, and finally, the desired colors are formed. That's why the colors from a real triple laser projector are vibrant and stunning as expected. Reaching 107% color gamut coverage of REC.2020, Casiris A6 reproduces colors that cannot be shown with DCI P3 or REC 709 color space. True laser empowers impeccable color accuracy and reproduction.
