The heat treatment is the procedure of repeated cycles of heating the wire at proprietary temperature and cooling it for achieving the required properties of the wire.
The colour do not determine the properties.
The surface coating like titanium carbide is doe over the wire which imparts blue colour to it.

Question
Rotary files prepared more conical canals in primary teeth than manual instruments. It reduced preparation time ( Musale and Mujawar,2014).
Additional reference:
Crespo, S., Cortes, O., Garcia, C., Perez, L., 2008. Comparison between rotary and manual instrumentation in primary teeth. J. Clin. Pediatr. Dent. 32, 295–298.
The ribbon shaped irregular surfaced root canal after preparation becomes conical, favoring a higher quality of the root canal filling,
and increasing clinical success. (Crespo et al., 2008)
Cleaning Efficiency
The probability of root canal deformation is reduced
due to its elastic memory and radial aspect that keeps the file
in the center of the root canal via wall support and inactive tips (Coleman et al., 1995).
Rotary files removes less root dentin than hand files in primary teeth.

Teflon tape should be used as spacer in inter appointment dressing.
Temporary fillings are displaced due compressed cotton and results in failed seal with bacterial growth in cotton.

Intracanal Teflon was also used for the dressing

It was found that Cavit and Cavit-W provided almost equal watertight seals, which was signicantly superior to the seal provided by Cavit-G. (Jacquot et al. 1996).
