If you're willing to do your own timing and race the beam, pump $0RGB values to $DFF180 with no bitplanes enabled at all.
Alternatively, on a AGA system you could use HAM8 mode and judicious use of colour palette to get 18-bit truecolour? Every pixel is 4 HAM8 pixels, displayed in SuperHiRes mode to look like 1 lowres pixel: First is the base colour, from one of 64 palette colours, which are 4 intensities of R, G and B in the MSB (e.g. 00xxxx 40xxxx 80xxxx C0xxxx times xx00xx xx40xx xx80xx xxC0xx times xxxx00 xxxx40 xxxx80 xxxxC0; 4*4*4 combinations = 64 colours). Next, three modifier pixels, modifying R then G then B to set the lower 6 bits of each.
