Lemon you say? This insulator is not your typical lemon colored Dominion CD 154. There is an area of peach in the dome and areas of green in the upper and lower wire ridge. The lemon Dominion CD 154 does not have areas of peach and green in the glass. While the color in this insulator is not strong enough to call it a two tone or tri-tone I do believe it deserves its own color designation. I will post another picture that shows this insulator with a lemon Dominion CD 154. Enjoy.
