8-BIT VS. 24-BIT TO APPRECIATE THE ADVANTAGES OF USING 8-BIT COLOR CONSIDER A 100 x 100 PIXEL IMAGE. THE IMAGE CONTAINS A TOTAL OF 10,000 PIXELS. USING 24-BIT COLOR EACH PIXEL WOULD REQUIRE 3 BYTES FOR A TOTAL OF 30,000 BYTES. USING 8-BIT COLOR WOULD REQUIRE: A LIST OF UP TO 256 3 BYTE ENTRIES TO DESCRIBE THE PALETTE. 10,000 BYTES FOR THE INDIVIDUAL PIXELS OR A TOTAL OF 10,768 BYTES.
