We tested Tokyo Blue #71 and I can assure you it is NOT accurate for color calibration. At least not by our standards. It was actually further off from reference than many blue gels we tried.





The most accurate was two (2) layers of a blue gel we came up with after 6 months of testing and evaluation. One (1) layer of blue gel did not work with any samples tested. In the end, we had to design a blue gel that was accurate but optically clear and still passes enough light to be useable.





Sourcing the best blue gel for WOW was a challenge. I think you will find the results two be very accurate using the Disney WOW World of Wonder calibration disc.
