CSS colors: depends on the monitor?

Are CSS colors separated differently on different monitors? Most importantly, will tools like the Digital Color Meter (on OS X, an eye dropper if you like) give me a different code depending on the monitor or graphics card?

Not. The color always remains the same. However, the physical perception of color can be affected by the display, the materials used for the display, lighting, and an almost infinite variety of things.

The dropper tool will always indicate the correct color. As the displays vary, the color (visually) will differ among them. However, in theory, the colors are the same everywhere. If you pick red with the eye dropper and draw an image and share it, it will show up as a red graphics on all systems (unless they are very glitchy!). If the display is missing red components or a red component is defective, the displayed color will not be red. Programmatically, the color is still red.



When designing on the web or working with graphics, always check with several different displays to make sure you actually pick the color you want as the displays differ.

In short: Yes and No.

The exact color values ​​are always the same. The exact rendering is changing, however.



  • First, there is the color depth: with a color depth of 8, 15 or 16 bits, the approximate value of the specified color should be used. Sometimes even with anti-aliasing.
  • The monitor itself can have very different colors, depending on its settings. It can be seen very easily if you have two monitors side by side. They will never show the same colors.
  • The color profile also affects color rendering. However, most people will not calibrate their monitors.

You shouldn't get different hex values ​​based on monitor, but you will get different end results depending on OS, monitor, graphics set, and settings.

The computer monitors the color numbers, so the numbers won't change no matter what monitor or graphics adapter you have.

Monitors will look different. There are many reasons for this; even two models from the same monitor may not look the same, especially if the settings have been changed. In most cases, they will be similar enough that no one will complain. There are some that you can purchase to bring them closer to the standard look.

Colors, regardless of the language used to display them, usually differ from monitor to monitor, this is due to different technologies that allow a different color space (profile) to be displayed. You can never have the same colors on all monitors, because CRT and LCD TVs display colors differently most of the time.

I don't know DCM, so I think you will have to try, but it would be much better if you tried to find the palette that displays best on most monitors, perhaps trying to look at CRT and LCD from different manufacturers.

PCs and Macs will indeed render colors slightly differently, although not necessarily because of the monitor.

For example, a Mac will render the color #FEFEFE in the browser, while a PC will render it white as if it were #FFF.
