Does anyone know what the recommended saturation level should be regarding the TMS9928A VDP as used on the ColecoVision?


I have played around with various values like 0.47 (same as the value used for the R-Y and B-Y values of the neutral colors and which makes the TMS9928A colors have similar values as the TMS9918A), 0.53 and 0.8 (the maximum luminance figure seen in the TMS9928A datasheet).


Thank you,
