Yellowbonnets:
The yellowbonnet is based on not painting the red warbonnet after painting the yellow.  It still retains the black stripe separating the yellow from the stainless/aluminum, and the silver understripe that runs along the bottom rivet strip.  Check out Ralph Back's article, A Yellowbonnet in Texas for more information and photos.

Bluebonnets:
[bb] The bluebonnet is based on painting Santa Fe blue where the red & silver warbonnets have the red.  Most units have the yellow and its black stripe the same as the red warbonnet units. An exception is the 343, which is missing the black stripe.  These units have black trucks, underframe & pilot, blue ends & anticlimber, full silver understripe, full yellow nose stripe with two vertical blue stripes between headlights & full cigar band, except as noted.
