Oddly I’ve experienced this to some degree. I have a scoped air rifle with an illuminated reticle that is capable of red or green crosshair/dot/circle etc. It also has a red laser mounted slightly below the scope. Both are sighted in for 30 yards and when I select the green reticle and turn on the red laser, they do appear almost yellowish when on target at 30 yards. Any closer or father from 30 yards and they diverge, with the red laser dot being above or below the scope reticle. I used to find this frustrating until I realised the amount of divergence actually became a crude range finder of sorts.
