IntroductionColor inversion is a common accessibility feature that inverts the colors of a display, often making it easier to read in a dark environment, for example, by turning white text on a black background into black text on a white background.In this post, I explore conventional approaches to color inversion and propose a new approach that preserves both hue and contrast ratios between colors.Existing approachesTwo common approaches to color inversion are RGB inversion and lightness inversion.RGB inversionThe simplest approach to color inversion is to simply invert each channel of an RGB color.In this post, we’re working in sRGB color, which is the standard space for representing colors on the web. Note that as a convention, I will refer to all color components as ranging from 0 to 1, even though they are typically represented as integers from 0 to 255—this is called “8-bit color” because each component is represented with 8 bits. RGB inversion is straightforward: each channel is simply inverted independently.Rinverted=1−RGinverted=1−GBinverted=1−B\begin{align*}R_{\text{inverted}} &= 1 - R \\G_{\text{inverted}} &= 1 - G \\B_{\text{inverted}} &= 1 - B\end{align*}While this type of inversion is easy to implement and very efficient, it comes with a large usability drawback: hues are rotated by 180, which makes it difficult to recognize colors.Use the widget below to see how RGB inversion affects hues. You can click the color swatches on the left (or above, on smaller screens) to change the colors.Text Contrast: 6.44 Foreground: #591a9f (0.054) Background: #c4cfe0 (0.617) Text Contrast: 8.6 Foreground: #a6e560 (0.65) Background: #3b301f (0.031)Lightness inversion in HSLTo fix this hue rotation problem, we can instead invert the lightness of the color, while preserving the hue and saturation. To do this, we convert the color to HSL color space (a cylindrical representation of RGB), invert the lightness, and then convert back to RGB. In HSL, the inversion is simply:Hinverted=HSinverted=SLinverted=1−L\begin{align*}H_{\text{inverted}} &= H \\S_{\text{inverted}} &= S \\L_{\text{inverted}} &= 1 - L\end{align*}This approach is still fairly simple and works well to enable color recognition. In fact, this appears to be the strategy used by Android when the color inversion accessibility feature is turned on.iOS and macOS have an accessibility feature called “Smart” color inversion mode, but it is not lightness inversion—instead, it is standard RGB inversion that avoids inverting images and videos so that their colors are not distorted. However, lightness inversion still has one issue: it distorts the contrast ratios between colors. This is because contrast

Ratio is not simply the difference in lightness between two colors, but rather a more complex calculation that will be explored in the next section.Use the widget below to see how lightness inversion affects colors and their contrast ratios.Text Contrast: 6.44 Foreground: #591a9f (0.054) Background: #c4cfe0 (0.617) Text Contrast: 3.63 Foreground: #9f60e5 (0.214) Background: #1f2a3b (0.023)Lightness inversion in LabAn alternative to inverting lightness in HSL color space is to instead invert the L* component of the CIELAB color space (or another similar space based on a perceptual color model). This approach has a few advantages over HSL inversion:The L* component is designed to be perceptually uniform, so the contrast ratios between colors are more likely to be close to their original values.Since inversion occurs in a perceptual color space, this strategy may produce more visually appealing results.On the other hand, it also comes with some tradeoffs:The math involved is more complex, so the color space conversion is more expensive.Notably, CIELAB has a much larger gamut than sRGB, so adjusting lightness in this space can produce colors that are out of gamut for sRGB, which will then need to be clamped or otherwise adjusted, potentially distorting the results.Text Contrast: 6.44 Foreground: #591a9f (0.054) Background: #c4cfe0 (0.617) Text Contrast: 6.54 Foreground: #dc94ff (0.436) Background: #222c39 (0.024)Novel approachThe new approach proposed in this article is to invert colors in a way that preserves both hue and the contrast ratios between color pairs.The math involved in this approach is a bit more complex, and details about the derivation are available in a separate post. Deriving a method for contrast preserving color inversion Seeking an approach to color inversion that preserves contrast ratios between colors. Jan 2024 DemoAs before, this widget demonstrates the effect of the new inversion algorithm on colors and their contrast ratios.Text Contrast: 6.44 Foreground: #591a9f (0.054) Background: #c4cfe0 (0.617) Text Contrast: 6.43 Foreground: #c9a5f0 (0.456) Background: #233043 (0.029)It’s not perfect—the contrast ratios are often off by a small amount, but this is due to the limited precision of the 8-bit sRGB color that we need to convert back to in the end, before calculating the results. Note, for example, that shifting even one color component by 1 bit (1/256th) often changes the contrast ratio by several hundredths. In theory, the contrast ratios could be identical in a higher precision color space.The code used to implement the algorithm in this demo is

GVERSE Inversion: Adding a Colored Inversion Volume into

Guitar Triads with Diagrams And Theory The tones of inverted chords are in a different order than the root positions. Inverted chords don't have the root note in the bass, instead they have the third or the fifth as the lowest note of the chord shape. Here is an example with the C major chord built with C-E-G, respectively the root (1), the major third (3) and the fifth (5). The bass note (the lowest note) is the root. This is the basic position also called "root position". This chord can be inversed in two different ways. One with the third in the bass and one with the fifth in the bass. Thus giving two inverted voicings. Root position 1st inversion (third in the bass) 2nd inversion (fifth in the bass) C E G E G C G C E Major triads - Chord shapes - Guitar diagrams Major triads are made up of a root (R), a major third (3) and a perfect fifth (5). Here are 12 neck diagrams to play them on the guitar, including 4 root positions with basses on the 6th, 5th, 4th, 3rd strings and their related inverted chords.

Of this interval are at C#-min-3rd.Repeating this for the 5th note / scale degree, the distance between C# and G is 6 half-tones, and the note interval name is diminished (d5). More details of this interval are at C#-dim-5th.Again the 7th note / scale degree, the distance between C# and B is 10 half-tones, and the note interval name is minor (m7). More details of this interval are at C#-min-7th.Finally, we have the name of the three note intervals of this 7th chord, and can now lookup the name of the 7th chord quality having these intervals.Looking at the Seventh chord table, the name of the 7th chord quality having minor(m3), diminished(d5) and minor(m7) note intervals is half-diminished 7th.And so the complete 7th chord Name prefixes the root note, C#, onto this quality, giving us the C# half-dim7 chord.Scale chord names using a,b and c notationThe chord symbol iiø could be followed by the letter a to indicate that it is C# half-diminished 7th chord in root position (ie not inverted) - B minor scale chord iiøa.Instead, iiø could be followed by the letter b to indicate that it is C# half-diminished 7th chord in 1st inversion - B minor scale chord iiøb.Letter c could be used to indicate that it is C# half-diminished 7th chord in 2nd inversion - B minor scale chord iiøc.Finally, letter d could be used to indicate that it is C# half-diminished 7th chord in 3rd inversion - B minor scale chord iiød.Scale chord names using figured bass notationIn place of the a-d symbols above, figured bass symbols could be used to indicate chord positions after iiø:So in this key, iiø7 refers to the C# half-diminished 7th chord in root position.For 7th chord inversions, iiø65 refers to the C# half-diminished 7th chord in 1st inversion, iiø43 refers to the C# half-diminished 7th chord in 2nd inversion, and iiø2 refers to the C# half-diminished 7th chord in 3rd inversion.The next scale chordThe next step will need to calculate the 7th chord whose root / starting note is next scale note.To do this, the first column we.
