Red Stripe helps people with color blindness distinguish various colors using stripe patterns filters and color alterations. Use it for ambiguous colors on signs and maps or simply to better understand the colors around you.

STRIPES

Oblique stripes on red, dashed stripes on green, horizontal stripes on blue. Pick the best stripes that best help you.

Stripes are visible by default on greens and reds. Those are useful for red-green forms of color blindness which is most common (deuteranopia, protanopia). Stripes on blue which are useful for those with a blue-yellow color blindness (tritanopia), but those are not enabled by default.

Stripes are good to distinguish other colors too. Stripes are more or less pronounced depending on whether the tint is closer to red, green, or blue. Stripes can be shown or hidden for any color.

HUE SHIFT

Red becomes cyan, green becomes magenta, blue becomes yellow, yellow becomes blue. This 180° rotation of the color wheel switches problematic colors to those you are more sensitive to.

LUMINANCE FLIP

Sometimes darkness makes colors harder to see. This filter makes dark colors become light and light colors become dark. The hue is left unchanged: what’s red stays red. Although if you want a fully negative image, you can combine with Hue Shift.

VIBRANCY BOOST

Increase color saturation and slightly darken uncolored areas. This may help for colors that are too subtle.

Note on Color Accuracy
Changing light conditions can affect color perception, both for the eye and the camera. Try to have good lighting conditions when taking pictures.
