A new formalism to generate pseudocolor spectra is introduced. Therefo
re, a parametric path in the RGB-color cube is derived to guarantee co
nstant brightness progression. The resulting spiral-like curve allows
the generation of various color spectra by adjusting the spiral's freq
uency and phase. The formalism allows the determination of the resulti
ng number of colors in dependency of both parameters. Therefore, these
spectra are particularly useful to represent 12 bit data on common co
mputer graphic adapters with 4096 displayable pseudocolor values inste
ad of 256 displayable grey intensities. In this paper, the spectra are
applied to medical X-ray images yielding an enhanced visualization of
the diagnostic information.
