Well known colour photograph which has appeared in various publications but worth showing again as a good, clear image for the colours of the tail codes.
'YoD-135' in yellow and 'YoD-198' in white. Note Zero behind Raiden also has yellow tail code and extreme weathering on Raiden. Unusual.
Note also Irving tail code 'YoD-198' is horizontal to ground line not airframe line.
In monochrome photographs it is difficult to determine whether codes are white or yellow. Did the colours signify anything? Hikotai?
