Most of the current research effort involves electrochromic (electrical potential), thermochromic (heat) and photochromic (light) materials.

And thermochromic pigments change color at a given temperature.

Role Changeability

No, still nothing. But the water has changed color.

Role A Changeability

Role B Changeability

The old goat has turned into the tender gardener.

Changed color

It's grown all dark.

These green leaves turn red or yellow in fall.

So the smell of vanilla, that might change the four on the left to brown and the one on the right to yellow. This matrix can produce thousands of different color combinations to represent thousands of different smells.

I wanted to blend in like a chameleon.

And finally, it's a rich lavender, and after a couple of thousand feet, it's ink black.

76. Chromogenic materials change colour in response to external stimuli.

And these dyes change color in response to odors.

It transforms through the magic of lighting.

Change of the roles and stereotypes of the sexes.

Display the current score. It turns blue if it is a highscore and red if it is the best local score.

The reason it has so much color is that it changes using lighting.

Cell loss, mutations in chromosomes, mutations in the mitochondria and so on.

Then reduces them to rusty rubbish.

Then made it dry and dark.

then made it a blackening wrack.

Then maketh it to stubble dusky.

And then makes it dark stubble.

And then turns it into light debris.

and then made it into a blackish straw.

Then turneth it to russet stubble.

and then turned it into a black scum.

then made it dry dark, flaky stubble,

And then makes it black stubble.

then caused it to wither away.

Then makes it dried up, dust colored.
