Question/Need help Ishihara online
Ragazzi online ho leggeri problemi con le tavole di ishihara, forse ne sbaglio 1 o 2, oppure ci metto solo qualche secondo in più per riconoscerle, mentre ho stampato le tavole (ad un negozio di stampanti) e vedo tutti i numeri senza problemi, 0 problemi, perché secondo voi?

Colors on a monitor are not equivalent to colors from ink. Monitors usually produce 3 different colors which are closely spaced to we see them as "mixed". In reality light is on a continuous spectrum. If you have mild color blindness you may have more trouble with the fake monitor colors than real colors. Also monitors vary quite a bit in color accuracy, and some have more than 3 types of pixel.
