Multicolor vs Blue broadcast sheet

Anyone know the significance between a multicolor and a blue broadcast sheet?
If never owned a multisheet car but have owned 70-71 where there was one or the other for the car.
Are there cars out there that have both (multicolor and blue) broadcast sheets?

Sorry if this has been discussed already. I did a search and did not see a previous topic that covered this.

Thanks

They were different revisions, the color highlight sheet was the 'new' version for the 1970 model year, it seems to have first appeared about mid-model year.

There have been countless cases of '68 & '69 revision sheets found in 1970 cars as well as blue & white & colored sheets found in the same cars.

The older sheets were often used up in the trim shop because the interior code was in the same spot as the newer sheets, so it was a great place to use up the old leftover stock.

Here are three together, the revision dates are in the top left corner. Front to back, 5/68, 4/69 & 6/69 with the 'color highlight only' note, these were all found in 1970 model year cars from Hamtramck;

Thank you!
