#colour profiles

Prompt art - October prompt: Halloween or spooky

I was just trying to paint a vampire, idk how it ended up here. (Notes of colour profiles below cut)

In the end this gave me so much grief with the colour profiles, I switch it to CMYK proof and it fix it. When I kept trying to export this it was messing up all the colours, the daks were super saturated and it wasn't possible to even see what was going on. I think when you copy textures it can change the overall profile? I'm not sure what takes precedence or how to forcibly change it back yet. Either way, something very strange and very specific is happening here, it isn't unique to FireAlpaca and it always seems to be most evident with saturated blacks. Around this area on the colour wheel.

I'm sure why it's happening will become evident over time, in the mean time, if you export a drawing and it looks totally different to what you drew, check the colour profile settings on monitor and in working environment. Switch it from RGB to CMYK or vice versa. I wrote on it briefly last month, I didn't expect it to come in handy this quickly. Just something to keep stored away for if it happens. This is a very niche topic that usually wouldn't come up.

COLOUR PROFILES

The imaging chain consists of the device the photograph is capture on, the device the photographed is displayed on and then the device that the photograph is printed on. Each device has a different colour profile and the way you see the image at the start (the capture) might not result (the print) in the appearance you originally saw at the start. Therefore to ensure that the final image results in the standard that you expect colour profiles are used. Different colour profile allows you to use a broader or smaller range of colours. The first image shows that if AdobeRGB is used to take a photograph of something bright and vibrant these colours will pull through in the final outcome however if sRGB was to be used those vibrant colours would be reduce. 

In certain cases, AdobeRGB is much better than sRGB as it can represent just under 40% more colours than sRGB can. Although this may be the case, sRGB is used more widely around the world as it came first and is used for electronic games, the internet, apps and on the majority of computers. When unloading images on the internet the colour profiles of the image will default to sRGB which as a results is not complimentary of your work as it will dull and darken the brighter and vibrant tones in your image, as show in the second image. The models skin tones are duller and chalkier than the original and even the red tone in the background has faded. Using sRGB can cause the loss of colours in the final print. Image three shows the difference of the range of colours AdobeRGB and sRGB represent. AdobeRGB can be converted to sRGB so that the photographs’ display for the web is correct however sRGB cannot be converted into AdobeRGB. 

To conclude, sRGB is more reliable for photographs that are being put on the web and AdobeRGB is more reliable for photographs that are being printed as it offers more accurate colours. 

ProPhotoRGB offers a much larger range of colours (shown in image four, the largest triangle) compared to sRGB and AdobeRGB. Although this may seem good, printers can’t produce this amount of colour on a photographic print.
