• this is supposed to be water in the sun, but i couldn't figure out how to make the color blue instead of rainbow without ruining the shine.. any ideas?

c.width=w=70;for(i=2800;i--;)x.fillRect(X=i%w,Y=i/w,X/9+1*(Y/7)+S(X/7-5*t),1),x.fillStyle=`hsl(\${U=191+i/55+S(t*9+i)*4},60%,40%,\${T(U)+.5}`

You can do it the lazy way, by simply adjusting the number range to lay within a single color hue, and shifting it towards the blue hue, blue is around 165 (light greenish blue) to 260(purplish blue)
