The Visolve webpage or download allows you to check to see if colours are sufficiently distinguishable from each other. This can help those with colour vision deficiency or colour blindness. You can upload an image and it will provide you with the original view and other selected options such as Red-Green transform, Blue-Yellow transform, Saturation increase, Red, Yellow, Green or Blue filter and with added hatching.
Visolve is also available as an app for iPhones or on Windows and Mac.desktop computers.
