Colour transfer with Solver SOP without additive colour accumulation.

[GlennimusPrime]

I'm using a Solver SOP to transfer colour over time from a single point to a grid:


When the coloured point moves back over previous positions, the colour is additive. What method can I use to 'paint' the current point colour to the grid non additively?

The issue is obviously my current vex inside the solver, because it uses additive math:

vector prev_col = point(1, "Cd", @ptnum);
v@Cd += prev_col;

I just can't wrap my head around an alternate technique to "paint" these colours over top of itself.

max might be cheap method

v@Cd = max(prev_col, v@Cd);

vop colormix or lerp seems more correct but requires a bit different approach of mixing with masking or so
