6.10.3 Color Rejection (Reducing the image color)
Acoustic noise caused by the bubbles or other oceanic factors may be displayed on the screen in a
weaker color like white, pale green, etc. Certain types of fish school such as squid and baby anchovy
may also be displayed in similar colors. In such a case, reduce the number of colors on the color palette
to better discern the school of fish and noise.
