How do I hold the Colour Card for proper readings?

How do I hold the Colour Card for proper readings?
Method to use to correctly read test kit results:

Hold the vial against the paper Touch the paper with the vial - it should not be separated from the color card even a bit. You can hold the vial directly on the spot already designed with the tube's shape or perpendicular to the paper (ie vial hold just above the color chips).

Orientation and quality of light is very important.

Light source must be behind you. Type of light is also important. If the reading seems to be strange or color is not appropriate, use sunlight behind you to verify the reading .
