Direct Color

Direct Color is a display technique that does not use CGRAM. Instead, the color value comes directly from VRAM. Direct color is available only on BG1, in the following background modes:

• Mode 3
• Mode 4
• Mode 7

Direct Select is the name of the bit that turns direct color on or off. ^[3] It lives at bit 0 of CGSWSEL (2130h).

Colors

This mode gets RGB values from the palette and color number. One tile can use 256 colors, and Layer 1 can use 2041 colors. The color value comes from 3 bits R, 3 bits G, 2 bits B from the pixel value, plus 1 bit from the palette value. However, palette 00 is a transparent color rather than black, complete black cannot be used. And, it is RGB443, full white cannot be used.
