Hi , i want dispaly 3 sprites of 16 bits width with 3 different colors (one each sprite)

Maybe

• Turn on reflected playfield
• Turn on the playfield pixels so that they show up behind each sprite, but nowhere else. You may need to adjust your sprites left/right to make them line up correctly.
• Invert your sprite graphics so they become stencils. This means all 0 bits become 1 and all 1 bits become 0.
• Leave the sprites black.
• Change the color of the playfield so the pixels behind each group of sprites are a different color.

It is similar in concept to how we came up with the 2 color 48 pixel kernel.

Yes, like Darrell says using the playfield is probably the best way. Then it is just balancing the timing of the writes to race the beam.
