NimbleTools provides several tools students may use to alter the color and contrast of the test. These tools include the Color Choice Tool, which changes text and background colors; the Color Overlay Too,l which allows students to place a colored overlay over test content; and the Reverse Contrast Tool which alters the contrast of the entire test interface.
