I've found that the yellow corresponds quite well to Tamiya's XF-60 (Now, that was the easy part)...
The "light blue" would be a mix (about 50/50) of their Medium blue (XF-18, I think, somewhere around that, anyway) and XF-19 Sky Grey. As for the dark blue, I would probably recommend a mix of XF-24 dark grey and XF-18 (or whatever it was

)
