Color grading
Color gamuts impact the final product by defining the range of colors that can be displayed on a specific device or medium. When color grading, colorists must work within the limitations of the target device's gamut, ensuring that colors are accurately represented and visually appealing. This may involve adjusting saturation, brightness, and contrast to fit within the device's color space, while maintaining the artistic vision and overall look of the film or digital content.

So, in order to make sure the colors appear appropriately on as many devices as possible, we stick to a smaller gamut? So, how does Pixar make sure its movies are visually attractive enough?(6 votes)
The film is originally created with a large gamut, then later, the color is 'graded' for different viewing mediums to fit the gamuts of those mediums. The video showed examples of these different grades at0:50.(3 votes)
Is there a reason why it is called a gamut?(4 votes)- Well it is called Gamut because it the complete range or scope of something, e.g spectrum, span or compass. These can all be linked to colour in a way.(4 votes)
This sound's especially hard on Blu-ray because everybody will play the movie on a different tv or computer monitor.
If I'm making a digital drawing that will be seen mostly on computer screens should I look for the most common gamut ? or I should always work on the best gamut I can?(4 votes)- Work with the region common to all gamuts of the computers you would send it to.(3 votes)
I am not very understand it, when I watch film on my computer, which color gamut I see, original or film?(2 votes)- You should see the 'digital' grade, or maybe a 'computer' grade. If you use a disk, however, you should see the 'home viewing' grade.(3 votes)
- How come lazers can't show pure red, green, and blue but apparently school computers can??(3 votes)
They can't as far as I know. Maybe you got that idea from the entirety of the CIE chromaticity diagram being displayed in the video? The thing is, the diagram cannot be displayed accurately on any device that can't produce completely pure wavelengths, so what is really shown in the video is an approximation. If you look closely at the diagram (without black triangles on it), you may be able to see something like dark creases (similar to the cyan, magenta, and yellow "creases" going out from the middle) making a triangle shape. That's because the diagram's saturation was increased so at least the colors in that triangle will be accurate on a typical screen the video makers expect people to watch the video in. Everywhere outside of the triangle, then, the saturation is shown as the maximum.(1 vote)
How can you tell the gamut of a computer, a film projector, etc?(3 votes)- can you make the tutorial for how to do that(2 votes)
why are lasers make more pure colours(2 votes)
Because they basically make waves.
Lasers can produce very small rays of light that are basically waves of pure light.
Hope that helps!(1 vote)
- i understand the diffrence between the projeter and monitotr but how do the programs affect the light given in each film which produces the amount of hls and rgb?(1 vote)
So wouldn't the laptop I'm doing this on not be able to produce the colors shown outside of the CIE chromaticity diagrams?(1 vote)

(ball bouncing) (lightbulb pinging) - We've seen that every display device can represent only a region of colors within the perceivable color space, and this region we call a gamut. But inside the computer, where colors are represented digitally,
they're just numbers, and they can represent the
entire perceivable color space. But when we send the film to a theater, we need to match the color space of the projector being used, and that's the job of the
color grading process. It's to fill out the color space available within that projector and sort of constrain any colors that don't fit within that device gamut. And that's why I'm joined here by Mark Dinicola, our colorist. Hey Mark. - Hello again, Dom. - [Dom] So tell me about
some of the different types of grades that you do for a movie. - [Mark] Well, we do the film grade; the digital cinema grade, that's for digital projectors in theaters; as well as grades for home viewing in both high definition and standard definition. - So film versus digital grading? What's that like? - [Mark] Well, as you
mentioned color gamut, the film has a totally
different color gamut than, say, digital cinema. Especially film, the
brighter saturated colors aren't as available, so say on Cars 2, where we had McQueen, a
bright saturated red car, we had an issue with the film grade. We had to decide, is it more important that he's bright and saturated, or is better to have proper contrast? - Wow, okay. Any other stories or
challenges on films past? - Pretty much any film that has red. Inside Out was an interesting one. It was a very saturated film, with so many different colors, like Bing Bong is bright pink. He tends to go brown on film, so we had to carefully
craft the grade for film for that movie to make
sure he stayed pink. - So in the next exercise,
you're gonna have a chance to explore what some of the
different gamuts look like with some scenes from our movies, and we're gonna ask you a few questions to make sure you understand the concepts. Thanks for sticking with us. Enjoy!
