These Morph Mugs - or
Chameleon mugs - are black or dark blue on the outside in
regular temperature (see photo) but as soon as a hot liquid is
poured into them, they color-change into a white exterior to reveal their
full-color gift mugs decoration.
These new heat-sensitive, color-changing
morph gift mugs are now available on a limited basis and carry a price
increment over our regular, full-color, custom-decorated and
personalized coffee gift mugs.
Note:
Our black morph mugs present the greatest "surprise" effect
as only
about 10% of the printed image (below the black surface) can be seen
when the mug is cold. When the mug is hot, all 100% of the image will be
revealed.
The Blue mug however allows about 20% of the image
to be seen when cold. Many customers like this effect as it's teasing
the viewer to some extent as to what else will show when the mug is
warmed up, as well as keeping the mug
somewhat "alive and decorated" even when cold.

Chameleon, common name for certain lizards
that are well known for their ability to
change
colors.
The chameleon changes color when it is frightened and in response to
light, temperature, and
other environmental changes.
