My Gists


COLORSPACES - The Primal Frontier A brief Look at the math that helps model how we see.

On PASSWORDS: 0u+W!+h+h3_01d-InWithTheNew! In other words, "Out With The Old - In With The New" a realistic discussion on password security, with a more realistic approach to reducing "crackability". HINT: we've all been doing it wrong, LOL.


Part I:Orange You Wondering About Contrast? Answering some contrast questions, and demonstrating a real solution to the infamous orange conundrum.

Part II:The Lighter Side of Dark Backgrounds An article comparing some parts of APCA with the old WCAG 2 contrast methods.


Part I:For The Luv of Color An article comparing CIE Lab and Luv colorspaces

Part II:Will Work for Color A follow up article on working spaces and related considerations. Introduces the concept of "Web Working Spacelets".

My Repos

SAPC and APCA The WCAG3/Silver Contrast Method and Algorithm. This is the canonical source for the latest version of APCA.

SeeLab This is a library for sRGB colorstring parsing and CIE processing. Includes XYZ, xyY, Lab, Luv, LCh and more!

TinyTrim This is a CSS sheet of terse classes, useful for quick adjustments without having to add a style="" great for site development when you have a client watching and breathing down your back, LOL.

Color-eaSSy Color-eaSSy is a CSS color stylesheet with a terse but easy to use methodology for color classes — in development, some of this is in TinyTrim

My Issues and Comments

Here is an INDEX of some of the larger and in-depth issue threads or posts I've created or been involved in on GitHub, which may contain useful information and research. Some of the information here may be superseded as some of these thread date back to the beginnings of the contrast research project. I'm making this list largely for myself to collate the still relevant information into a single FAQ or similar explainer document. Someday.

My Non-GitHub Content

profile for Myndex on Stack Exchange, a network of free, community-driven Q&A sites

SAPC Contrast Research Tools The WCAG3/Silver Contrast Algorithm beta site. Includes interactive experiments that demonstrate the concepts.

Color Vision Deficiency Simulator This simulator demonstrates the way someone with a Color Vision Deficiency (incorrectly labeled "color blind") sees colors.

The Art and Science of Applied Probability

In this career, I was using Applied Probability Methodologies for the Risk Assessment of short term ROI predictions related to high-variance cash-flow opportunities in finite-sized non-cooperative bidding groups where information is obliquely concealed as a function of multivariate strategies facilitating the predominately range-based tactics driven by randomized but nevertheless deterministic outcomes.

(…Uh… this is more commonly known as Texas Hold ’Em Poker…)

    # Where's The Luv?
    ### An Examination of the CIELAB and CIELUV colorspaces.
    It is exciting to see so many new color features for the CSS Color Module. There are nevertheless a couple items that resulted in a "raised eyebrow response". This Gist is mainly going to focus on one: the use of the LAB version of LCh instead of LUV LCh, which may be better suited for the task but appears to have been dismissed as if irrellevant.
