I used size, shape, value, orientation, blur, 3D, and background color to portray the meaning of white on black.

I used size, shape, color, orientation, location on the page, and the background color to make the word quiet look sad, timid, or not very loud.

This is the color page, the emphasis is the word reverberation, then the white circle is moving to the top right corner.

This represents a mushroom cloud, which are normally loud. the emphasis being the ring around the "stem" of the cloud.

This is the pattern page, the emphasis is the pair of headphones in  the center and the sound waves move around the page.
