For Atlas machines that were sold as Craftsman, Krylon Regal Blue is a close but not perfect match.
Original Atlas machinery was a a dark gray but I have not heard of an exact match being made yet.
For Craftsman/Walker-Turner 12" bandsaw, another close but not perfect match is Benjamin Moore UTILAC High Gloss Metal and Wood Enamel - Classic Navy #490 36.
Scott Andrew added:
I recently restored a 1937-1940 Craftsman 6" Jointer. I spent considerable time to match the original color before stripping the machine to bare metal. I used Benjamin Moore latex metal paint in low-luster as the base coat, and high-gloss for the top coat. This jointer was manufactured by Walker-Turner.
Base coat Benjamin Moore ~IronClad Latex Low Luster Metal & Wood Enamel
Quart Ultra Base 363 4B BK - 12 BB - 1x6 MA - 9 WH - 10
Top coat Benjamin Moore Impervex Latex High Gloss Metal & Wood Enamel
Quart Ultra Base 309 4B BB - 16+1/4 GY - 2x3+1/4 MA - 6+1/4 WH - 5.5
I have a Craftsman Drill Press 103.0305, Valspar #65031 Royal Blue was a very close match to the blue I found under the hinge.

For light blue Craftsman Table Saws I've found the Rustoleum Satin Wildflower Blue to be closest.

Sears Royal Blue close approximations:
NOW (Sherwin-Williams) 21207 Royal Blue spray paint (ACE Hardware), Rust-oleum 334091 Satin Midnight Blue.
Sears Power-Bronze: Rustoleum 261415 Champagne Mist metallic spay paint is a very good match.

4.) Stand - Krylon "Tough Coat" product# A00329007, Machinery Blue/Gray spray paint 12fl oz, retail price $7.10
The problems and concerns I encountered while trying to place an order with delivery to my home in Cincinnati, OH are:
1.) Krylon does not sell directly to the public, the "Tough Coat" paints are only available through authorized Industrial Paint Retailers, and Krylon's 800 number leads to a 3rd Party Distributor's telephone number that may direct you to a 3rd party Industrial Paint Reseller based on your zipcode..
2.) In my zipcode area, there are only a 2 possible Industrial Paint Retailers that sell Krylon "Tough Coat" spray paint, they require a company account to be set up even though mine is a personal purchase for private use, and the combined paint can shipment had to be cross-shipped by UPS with an additional shipping charge from the Illinois Retailer's Distribution Warehouse.
3.) Most Industrial Paint resellers often do not carry Krylon "Tough Coat" paint in current stock due to possible low sales demand and/or limited shelf life.
4.) eBay and Amazon list these Krylon paint product#s, but the pricing is only per case and not for individual cans (12 per case). Sherwin-Williams Retail Paint stores cannot order Krylon Industrial Paints.
5.) Krylon only warrants the "shelf life" before application of "Tough Coat" paints to be 2 years from the date of manufacture
6.) Only Krylon "Tough Coat" primer is recommended for use other Tough Coat paints, or else chemical/adhesion problems may occur mixing different OEM paints.
