Quoted from ralphwiggum:
There are just far too many variables to say warm white in orange inserts, cool white in yellow inserts,
This is correct.
First, your answer will depend on playing in light or dark, a new game with clear inserts, or an older game with 30 years of ball wear, frosting that same insert.
All the answers work.
For orange, Natural white, warm white, or orange...sometimes a brighter orange like a 4 SMD.
Sometimes a clear orange for a new Stern with a clear insert...All personal taste, each one with a slightley different appearance. It depends on you, where the insert is on the playfield, and your taste.
Yellow is another story. In general, they suck. The color yellow will never have the same brightness as another color
say as a single 5050.
However, there are several ways to use yellow that look good.
Frosted 6mm or 8mm, ONLY as an indicator light, instead of a condom bulb.
In a frosted SMD. While the light output is not the same, because of a frosted lens, the yellow is dispersed and actually brighter or more noticeable then a clear. In some GI uses, this is the perfect choice for yellow.
Lastly, when you truly want Yellow or Orange, try our Op-Max.
We had a need from John here on the boards, at the APE show, to match other colors in Pop Bumpers in an EM
Game. He tried every bulb we had, and settled on a yellow Op-Max, as it is the brightest we know of, and it matched the brightness of the others...
The yellow and orange in this bulb need to be seen to be appreciated.....they are something unique.
Thant being said, they can be overkill for some inserts, because of a brightness bleed to other inserts.
Not always, depends on the game....but I have put them to good use.
Just watch the plain clear yellow LEDs....use alot less use then people think......I use yellow Optix Super Flux in my yellow inserts as I see the same brightness, as others, no ghosting less flickering, and the brightness matches well.
