"Bluestreak" likely refers to a shade of blue used by IVECO, specifically for their IVECO BUS brand. IVECO BUS has adopted a new brand identity featuring "Energy Blue," a shade of blue meant to represent the brand's dynamism and innovation. This new color is a key part of their updated brand image. 

While "Bluestreak" isn't a universally recognized color code within IVECO's broader range, the "Energy Blue" used by IVECO BUS aligns with the description of a vibrant, forward-looking blue. IVECO Group, the parent company, has also undergone a rebranding, unveiling a new logo and renaming itself from IVECO to IVECO Group.
