Assuming the red dot is the origin of the ray, going in the direction of the
first point (green) I want to find a point along the yellow line that is the
same distance from both points (Blue and Green).

Simple- make a line from the blue to the green.  Bisect it with a
perpendicular line.  The point of intersection of the bisector and the yellow
line is equidistant from both blue and green.

Cheers!

Sometimes the simplest methods evade us, I learned something here...

No need to specify that- it all happens on a single plane anyway, every
time.  The entire process is 2D.
