two X's, the normal trace the orange
line, but the majority of of those with
color vision deficiencies are unable to
follow the line or follow a line different
from the normal one.

41. •In tracing the winding line between the
two X's, the normal trace the bluish-
green line, but the majority of those
with color vision deficiencies are
unable to follow the line or follow a line
different from the normal one.

43. •In tracing the winding line between the
two X's, the majority of those with red-
green deficiencies trace along the line,
but the majority of the normal and
those with total color blindness are
unable to follow the line.

45. •In tracing the winding lines between the two
X's, the normal trace along the Purple and
Red lines, In Protanopia and strong
Protanomalia, only the Purple line is traced,
and in the case of mild Protanomalia both
