Arbiter of Ash Coridor Attack - not enough color distinction or time to react

"Coridor" attack.
Is very hard to see wheres safe line.
And no time to react.

In the time where i can see wheres safe to go i already dead.
Pls disctint colors of safe zones vs dead zones more.
Now its impossible. 5 deaths in a row.
Btw, no color blindness, perfectly calibrated oled monitor, no problems in any other part of game (t4 breach boss done, t4 olroth done)

Here struggle with t0 boss due lack of visibility
