The standard we aim at
Web Content Accessibility Guidelines 2.1, Level AA.
How it was measured
By measurement rather than by eye. Every text and interface colour on this site is computed against the ground it actually sits on: the colour's transparency is composited over that ground, any transparency inherited from a parent element is folded in, and the resulting contrast ratio is calculated to the WCAG 2.1 formula. Where an element can appear on more than one ground, the worse of the two governs.
Alongside that: the site was operated with a keyboard alone; checked at 320 pixels wide and at 200% zoom; and checked with the operating system's reduced-motion setting turned on.
What has been found
- No text on the site is set below a contrast ratio of 4.5:1, at any size.
- No text on the site is set below 11 pixels. From 15 to 19 August this sentence carried an exception: the drawing of a phone lock screen on the home page contained three lines of type that rendered between 7.5 and 8.9 pixels, because type inside it scaled with the picture. The drawing was rebuilt on 19 August with every size inside it set directly, none below 11 pixels — measured in the browser before this sentence was restored, not assumed from the stylesheet.
- Every interactive element can be reached and operated by keyboard, in a sensible order, with a focus outline that is visible against its background.
- Colour is never the only thing carrying a meaning. The question rows, for example, show their open or closed state by the direction of a marker as well as by anything else.
- There is no horizontal scrolling at 320 pixels wide, and nothing is cut off or overlapping at 200% zoom.
- There are six moving things on the site, and every one of them stops if you ask for reduced motion. Two are drawings of a phone: one at the top of the home page, which changes the word it is showing once a second and cycles through the six languages; and one beside the account of the method, which steps through the six panels of a lesson at the same rate. Both are built from the page itself rather than from a file. The third is a slow glow behind the first of those phones, which brightens and dims over nine seconds. The fourth is the page arriving as you scroll to it: most sections now move as they come into view, and they do not all move the same way — the six languages resolve one after another, the method’s three steps fill a rail beside them as each arrives, the six things we will never do have their struck-through line warm from nothing after the words are already readable. The fifth is the background, which changes tone from section to section and carries an amber light that moves to a different quarter of the screen as you go down. The sixth happens once: the top of the page assembles itself over about a second when the page opens.
- The statement here used to describe a recording of the app. There is no recording on this site and no sound anywhere on it — we checked for a video or audio element on every page and found none. The panel beside the method, which that sentence described, is a drawing built from the page in the same way as the one at the top. Everything that sentence said about how a recording started in different browsers, and about a still frame standing in its place, described something that is no longer here, and it is removed rather than reworded.
- The last three of the six are new on 8 September 2026 and none of them carries information. Everything they show is also written in words on the same page, and switching them off removes no content, no wording and no step — the page is simply still. If you have JavaScript turned off, none of the three happens at all, and the page you get is the one that was here before them.
- The moving light on the background passes underneath text, so we measured what it does to the reading. At its brightest point, directly beneath type, the lowest contrast anywhere on the page is 5.60:1, on the quietest of the three text colours. The ordinary body colour reads at 9.20:1 or better on every ground, and headings at 13.16:1 or better. The floor is 4.5:1. These were measured by compositing the light over each of the five backgrounds and calculating, not estimated by eye.
- The two drawings each carry their own Pause control, positioned directly beneath them, and the two are separate: stopping one does not stop the other. Neither control is shown until it is reached — each appears when it receives keyboard focus, as the skip link at the top of every page does, and each is announced to a screen reader whether or not it is visible. Once pressed, that drawing stays stopped.
- If you use a mouse or touch alone and want nothing on the page to move, turning on your operating system’s reduced-motion setting stops all six before any of them starts. We know this is a weaker position than a control every visitor can see, and it is a deliberate one.
- When reduced motion is requested, a single complete word stands in the first drawing and a complete panel in the second, and either can be started from its control if you want to watch it. Nothing else on the page moves, and nothing is hidden waiting to be scrolled to.
- Neither drawing is read out to a screen reader beyond a single description of what it depicts. Their interiors are not announced, because the words in them change several times a minute and say nothing the page does not already say in writing.
What has not been assessed yet
We would rather say this than imply a completeness we have not tested for.
- Screen-reader passes with VoiceOver and TalkBack have not yet been run against this site. That includes both drawings of a phone and both of their Pause controls, which have been checked by keyboard but not with a screen reader running, and it includes the motion added on 8 September 2026: the entry of each section, the changing background and the opening sequence have been checked for what they leave behind when switched off, and not with a screen reader running.
- The lock-screen drawing has not been checked on a browser that does not support container queries, which is the mechanism it uses to hold its proportions at any size. Where that support is absent the drawing is expected to render at the wrong text sizes rather than to disappear. It has not been seen in that state, and saying so is more useful than predicting it.
The European Accessibility Act
The Act's requirements bite on the Lumessa app and on anything sold through it rather than on this informational website. We are aiming this site at the same standard regardless, on the view that a site that fails the test is not made acceptable by being out of scope.
