fire line meanings in battle

[drhyed]

When engaged in battle there are several different lines going from my ships to the enemy

red dashed lines
blue dash dot lines
yellow dotted lines

what do each of these lines represent?

the manual references fire lines, which I assume these are, but I cant find specifics

[WLRoo]

Red is your primary battery

Yellow is your secondary battery.

The blue/green is incoming enemy fire
