Different devices can’t always display the same range of colours, so your camera may be able to record a wider range of colours than your computer monitor or tablet can display, for example – in other words, the monitor offers a smaller ‘colour space’. To get round this, there are two main RGB colour spaces you can work on. The sRGB colour space is a smaller, universal colour space that practically any device can match. Adobe RGB is a larger colour space that your camera and printing systems can capture but your monitor probably can’t, which means some complex workarounds and pitfalls and really needs a switch to a more complex colour managed workflow. sRGB is the simplest solution, and (though some will debate this) you’re unlikely to see any real advantage to Adobe RGB in everyday photography.
