Color opacity task

Run this application online

This short-term memory task requires a fine distinction of shades between colors. By adding the number of choices, the task becomes more difficult because the colors offered become more similar to each other.

This task is based on the Opacity-Transparency of the displayed colors.

Opacity is the degree to which content behind an element is hidden, and is the opposite of transparency.

When referring to color, transparent color is a color that lacks color or a color that's the same color as the background.

A limited number of settings can be changed within the application.
