From wikipedia, the meter is defined as the length of the path travelled by light in a vacuum in 1/299,792,458 of a second. I’ve been reading about “color accuracy” and truecolor on the Mac, but I’m not clear on what “accuracy” means in this context. Accurate to what? Wikipedia defines blue as perceiving “a dominant wavelength between approximately 450 and 495 nanometers,” which seems to define it subjectively.
What’s the standard to define a color? What makes one blue more accurate or correct than another?
In: Technology
Color accuracy is less to do with the physics of light and more to do with our mechanical ability to reproduce colors accurately on different mediums. Imagine if a photographer was taking a photo of something with low contrast. If he worked with it on a computer with high accuracy but then printed it on a printer with low accuracy, he’d think the image is fine but it prints horribly. Or vis versa; he can’t see details on his monitor but they appear quite clearly once printed. Alternatively, if he has two different monitors with two different sets of color accuracy values, his images will look different on each monitor. Technologies like truecolor allow monitors to replicate different lighting or printing conditions so that the image will accurately reflect the source object’s appearance or will match the printer that will print the image.
