Do they look blue to you? (I always thought the colour as purple 🙂 )
Joke apart.
The easiest method would be to apply a "hue/saturation" (same as a Hue/Saturation node in blender, but as an adjustment layer in Photoshop)
And move the hue slider until it fits
You can use the colour sampler tool to check if the colour is the right one.
