The colour blindness simulator is a tool to use for how that image or colour appears to a person with different types of colour blindness. You can check the protanopia, protanomaly and …

There are many simulation methods, with varying degrees of accuracy. Several are proposed here and they all have been carefully implemented in DaltonLens-Python by reviewing the …

As it is not not so easy to describe color blindness it comes in handy, that some smart people developed manipulation-algorithms to fake any form of color vision deficiency. The algorithms …
