The Hitchhiker's Guide to Digital ColourThis is the full HG2DC Questions listing!
We’ve been talking about radiometric light ratios here for the most part, specifically regarding the final output from a display. In an effort to understand the subsequent questions that follow this one, we are going to need to fill in some further details about what “a quantity of light” means in a way that will […]
Phew. It’s been a long time coming, but the time we have invested is starting to pay off! We can actually discuss colour in a meaningful way, and with the introduction of perceptually uniform maps with Question #15, we can even compare colours or get a sense as to “how different” chromaticities are! And we’ve […]
We’ve touched on the importance of the CIE’s chromaticity model, and its relationship to visible light spectra as the single most important framework for pixel pushers to get a firm grasp on to understand all of colour. Some folks may also likely have come to realize that the two dimensional representation is missing some important […]
Sixteen questions! It has taken us sixteen questions to even begin to describe the term “Colour Space” with any degree of useful communication. We can hop right in to our question… Question #17: What is an RGB colour space? Careful before you scream out “YOU JUST SAID RGB IS A COLOUR SPACE!!111!!”. See the article […]
Recall back to Question #13 where we explored how chromaticities are discussed. You may have wondered where that triangle went, and why I removed it in the subsequent diagrams in Question #15. Why did we have to learn about chromaticities instead of RGB values? Because, as you have hopefully learned from the preceding batch of […]
We have laid some tremendously important groundwork in the most recent questions. Within that, even if you have seen or heard about the concepts introduced prior, it is helluva important to make sure that what we have explored is extremely clear. Sadly, the chromaticity diagram explored in Question #13 needs a bit of a revisit […]
Phew. It’s been quite a few questions to be able to finally, just about, almost, kinda, sorta discuss what is “white”. The key here is to attach “white” to terms that will not only make sense to you, the happy pixel pusher, but also be able to discuss it in ways that apply to your […]
Another big word for someone who likely only wants to focus on painting on their iPad Pro. The bad news is that exploring new terms takes time and energy. The good news is that there is likely no more an important term for a pixel pusher to learn. Why haven’t you heard of it before? […]
Brighter? Lighter? More light? Less light? Where the hell does physics and energy fit into all of this? Arrgh. If we don’t have a clear grasp on what linear means and it’s relationship to digital colour, we are going to have a hard time discussing deeper subjects. So what the hell is happening when we […]
Given we’ve hit a milestone in that we are approaching the teens in our question count, the time has come to start diving into the murky side of digital colour for all of you lovely pixel pusher types. Up to now, you’ve probably noticed that we have successfully managed to avoid the sticky subject like […]
