Early black-and-white television was incapable of differentiating between subtle color and tonal contrasts, and television sets often markedly cropped the edges of the signal. Two-dimensional titles were only on the air for a few seconds, requiring rapid viewer comprehension. To overcome these problems, designed on-air graphics from the center out, using simple symbolic imagery with strong silhouettes and linear properties. Emphasis was placed on concepts that quickly captured the essence of each program. This designer was the grandson of a slave from a northern Kentucky plantation and the first African American to achieve prominence as a graphic designer.

Georg Olden

Explanation:

Born as George Elliott Olden  in November 13, 1920, he grew up to be one of the pioneer Africans to work professionally and with renowned T.V stations like CBS as a graphic designer. He solved the problem of old black and white televisions that were unable to differentiate between subtle colors and tonal contrasts. He developed on-air art and made striking designs such as the icon used in the television program, To Tell The Truth which featured from 1956 to 1978.

He designed the statuette for the Clio awards held in 1962 which was the first of its kind. He designed postage stamps and this was the first time such a thing was done by an African.
