Total Color Blindness Test Lines

Test Plate 1:

Normal will trace the blue-green line between the two X's.

The majority of those with colour vision deficiencies will be unable to follow the line or will follow a line different to the normal one.

Test Plate 2:

Normal should trace the line connecting the purple and the orange between the two X's.

Red-green deficiencies should trace the line connecting the purple and the blue-green.

Total colour blindness and weakness cannot trace any line.

Test Plate 3:

Normal will trace the orange line between the two X's.

The majority of those with colour vision deficiencies will be unable to follow the line or will follow a line different to the normal one.

Test Plate 4:

The normal should trace along the purple and red lines between the two X's.

In protanopia and strong protanomalia only the purple line is traced and in mild protanomalia both lines can be traced but the purple line is easier to follow.

In deuteranopia and strong deuteranomalia only the red line is traced and in mild deuteranomalia both lines are traced but the red line is easier to follow.

Test Plate 5:

Normal should trace the line connecting the blue-green and the yellow-green.

Those with red-green deficiencies trace the line connecting the blue-green and purple.

Those with total colour blindness cannot trace any line.

Test Plate 6:

Both normal and those with colour vision deficiencies can trace the winding line between the two X's.

Test Plate 7:

The majority of those with red-green colour blindness can trace the winding line between the two X's.

The majority of those with normal and total colour blindness are unable to follow the line.
