homm/color-filters-reconstruction is a GitHub repository with a number of tools that help to automatically or semi-automatically deconstruct the color filters applied to a picture by such services as Instagram, Google Photos, and others.
Here’s how it works:
This method is based on three-dimensional lookup tables and their two-dimensional representation: hald images. The core idea is simple: a sample hald image with a uniform color distribution is processed using a target color filter with an unknown transformation algorithm. The processed hald image can then be used as a filter for a very accurate approximation of that target color transformation.
A resulting hald image could then be used in various software such as GraphicsMagick or Adobe Photoshop. You can implement those hald images in your iOS or macOS app with CocoaLUT. Also, hald images could be converted to the 3D LUT cube file format, which is common in a great number of video editing software.
“Color: From Hexcodes to Eyeballs” is one of the best articles on color theory and the relationship between color coding, hardware, and human color perception, that I’ve seen in a long while. Scratch that. That I’ve seen EVER!
I was already somewhat familiar with the subject, so I scrolled through the article twice, quick read it, and will have to spend even more time with it. But if you want to really understand how this part of technology works with humans, it’s the best resource that I can send you to.
Practical Color Theory for People Who Code is an excellent guide to color theory for developers. If you’d rather rely on simple formulas for color combinations, than on your own authentic eye, this guide is for you.
If you are not a graphics or web designer by trade, but do have an occasional need for a color scheme that just works, Adobe Color CC is the tool just for you. It’s web-based – so there is no need to install anything, it’s free, and it’s super easy to use. It supports a variety of color rules – analogous, monochromatic, triad, complimentary, compound, and shades – just pick one, and drag the markers around the color circle, until you are happy.
I’ve seen and used a bunch of similar tools, but I think this one works the best of them all.
Here is an interesting web design idea that adds uniqueness to the website : use a random font for post titles, and use random color schemes for each post. To hell with consistency you say? Well, apparently, being random is being consistent too.
Picked up the thought from this blog post.
