French to English Marketing Printing & Publishing colours in printing

Hi, this is in a document regarding brand identity for a company, this part of the document describes the colour palette which may be used for the company's logo.

'Tons directs' appears as part of a list of different elements of the company's logo for use in print communications, as follows:

Les logos: pour communication print
4-couleurs
Tons directs (pantone)
Quadrillages
Monochrome

The closest translation I've been able to find is 'spot colours', could anyone confirm if this is correct please? Thank you.
