Yeah not sure why TOTS made these blue, the coveralls were actually charcoal grey "Workrite Ultra Soft Work Coveralls"in Halloween 2018, they just look blue in low lighting. The coveralls used in Halloween (1978) are "Tex-Green” Sears Tradewear Coveralls which look grey and green in various lightings and blue at night. The coveralls used in Halloween II (1981) were Spruce Green Sears "Work and Leisure" Coveralls. But they look different colors base on the different lightings. 40 years ago it was believed that H1 was charcoal and H2 were green, so that is the colors I do for them mostly or I do whatever color customers want. I have done H1's in blue and green also over the years as requested. My first pair was back in the early 80's which were green.
