The pattern has complementary colors in the
middle of the R, G, B color bars. If there is
delay in R, G, B, the border lines of some
color bars will change to white.
The pattern is an R, G, B color mixed
checkerboard. The color palettes are
editable, and the patterns can be triangle,
circle and square.
The pattern has R, G, B three colorbars from
left to right on the upper side, and three
brighter R, G, B colorbars from left to right on
the lower side. The pattern is used to check
if the R, G, B connecting order is correct and
if the circuit is working normally.

comparing the contrast of colors.
