Accessibility Overview Workbook Series 7: Invert & Color Features

Section 8:  Invert Colors

In this workbook series we will learn how to access basic accessibility features on a mobile device running iOS (iPad/iPhone). Today’s lesson will cover section 8 (Invert & Color Features).

To access the Invert Colors feature:

Settings→Accessibility→Display and Text Size. 

Toggle Smart Invert and/or Classic Invert on. 

(For older iOS Settings→General→Accessibility→Invert Colors. 

Toggle Invert Colors On).

Per Apple Support (https://support.apple.com/en-us/HT207025)

“Turn on Invert Colors

If you benefit from viewing items against a dark background, you can use Invert Colors to change how content is displayed on your screen. 

Smart Invert reverses the colors on the display, except for images, media, and some apps that use dark color styles.

Classic Invert reverses all colors on the display.

Turn on Color Filters

If you have color blindness or other vision challenges, you can use Color Filters to help you differentiate between colors. Color Filters can change the look of things, like pictures and movies, so you might want to use it only when needed.

Open the Settings app, then tap Accessibility > Display & Text Size > Color Filters. You'll see three examples of color spaces to help you select an option that fits your needs. Swipe left or right on the examples to find a filter that works best for you.

Choose a filter (Color Filters)

When you turn on Color Filters, you can choose from four preset filters:

  • Grayscale (a range of gray shades from white to black, as used in a monochrome display or printout. https://en.wikipedia.org/wiki/Grayscale)
  • Red/Green for Protanopia (*People suffering from this kind of color blindness are called anomalous trichromats . Protanopia Color Spectrum Protans have difficulties to distinguish between blue and green colors and also between red and green colors.)
  • Green/Red for Deuteranopia (*DichromatsDeuteranopia (also called green-blind). In this case the medium wavelength sensitive cones (green) are missing at all. A deuteranope can only distinguish 2 to 3 different hues, whereas somebody with normal vision sees 7 different hues.)
  • Blue/Yellow for Tritanopia (*People affected by tritan color blindness confuse blue with green and yellow with violet. So the term blue-green color blindness would be more accurate because the colors blue and yellow are usually not mixed up by tritanopes.  People affected by tritanopia are dichromats. This means the S-cones are completely missing and only long- and medium-wavelength cones are present.)

Adjust color intensity

You can adjust the intensity of any of the Color Filters to fit your needs. Use the Intensity slider to customize a filter that's more intense or less intense.

Adjust Color Tint

If you have color or light sensitivity, tap Color Tint to change the hue of the entire display on your iPhone, iPad or iPod Touch. Use the sliders to adjust your display's hue and the intensity of the effect.

Reduce White Point: Reduces the intensity of bright colors.”
