Hi @Marin_Takanov , thanks for flagging this and for the clear repro steps.
You’re running into a known discrepancy: after the new color palette was introduced in the Asana web UI, the Projects API color field behaves inconsistently between read (GET) and write (POST/PUT). Unfortunately, due to some legacy dependencies, we’re still working through the remaining changes needed to make read and write fully align.
In the meantime, please use the following mapping between the “write” (old) color values and the “read“ (new) colors:
