Introductory Informations wordword = 2 bytes = 2 bytes longlong = 4 bytes = 4 bytes palette = Hardware color palette, stored as 16 words. First wordword = 2 bytes is color register zero (background), last wordword = 2 bytes is color register 15. Each wordword = 2 bytes has the form: Bit: (MSB) 15 14 13 12 11 10 09 08 07 06 05 04 03 02 01 00 (LSB) 0 0 0 0 0 R2 R1 R0 0 G2 G1 G0 0 B2 B1 B0 R2 = MSB of red intensity R0 = LSB of red intensity G2 = MSB of green intensity G0 = LSB of green intensity B2 = MSB of blue intensity B0 = LSB of blue intensity Intensity ranges from 0 (color not present) to 7 (highest intensity). Example: { red = 7, green = 3, blue = 5 } -> 0735 (hex) Caveat: It is wise to mask off the upper four bits of each palette entry, since a few programs store special information there (most notably Art Studio).
