Colours appearing in my transparent object, cant seem to work out why

[Dave Ross]

If the material came with the file, it may be in the material itself.
Next, what kind of lights are in the scene … is there a sun object ?

If it’s still a problem, a scene file would be helpful.

and green in the image too. All looking like backface showing through the transparency. Definitely a scene file would help.

sadly i cant provide a scene file as im working on a job, and its against contract

But i Have 2 area lights with area shadow
i also have 2 sky objects one as a gi light and a hdri reflections

is there any thing i can do to slowly try to eliminate the cause
also what do you mean by backface showing through the transparency

[Brian Jones]

I say backface because everywhere the color is (red and green) it looks like it’s coming through the translucent plastic not reflecting off the surface – the sole exception is the green on the back support with the slot in it, that looks like it could be backface or reflection. Can’t really tell what’s causing it, can you remove the device and replace it with simple cylinders with the same materials and the same lights? You’d need to Save with Assets as the images used may have something involved.
