Contrast Scout
Sample two colors
Point the finder at a label, a spool of thread, a paint chip, or a sign. Save sample A, then sample B. You can also sample from a photo or the color picker.
For makers, not web mockups
Choose thread, paint, and labels you can actually tell apart.
Contrast Scout is a camera-assisted notebook for color-vision-deficient makers and accessibility-minded hobbyists. Sample two physical colors, get a contrast ratio plus a plain-language craft result, save swatches, and preview common color-vision differences.
Readings are estimates affected by lighting. Contrast Scout is not a safety certification.
Read it in workshop English
See the WCAG contrast ratio and a plain-language result: easy to tell apart, readable, large marks only, or may blend. Previews show small labels and large lettering.
Keep a physical palette
Save swatches on your iPhone or iPad like chips in a shop notebook. Simulate protanopia, deuteranopia, and tritanopia before you commit to paint or vinyl.
Built for the bench, the sewing table, and the sign shop
Most contrast tools assume a sRGB mockup. Contrast Scout starts with the material in your hand. Camera frames are processed on device. There is no account and no photo upload.
