Summary of Issue: Add reference to 1.4.1
Comment (Including rationale for any proposed change):
Although color is treated in 1.4, it is nonetheless a sensory characteristic. Should it be added to the list, with a note referencing 1.4.1?

Proposed Change:
\"...components such as shape, *color,* size, visual location, orientation or sound. (Level A)



Note: issues specific to color are covered in Guideline 1.4 (see specifically 1.4.1).\" (or similar)
