Indesign RGB colour

[Harribone100]

Hi
A client has sent us their brand style guide and quite rightly insists we use their brand colours but when I mix up the RGB colour values or sample from their brand style guide my RGB colours are different to theirs, even though my swatch palette says they are the same. You can see this clearly in the screengrab attached (my swatches are the smaller squares). Can anyone please explain why this is and what I am doing wrong? Thank you.

Do they have the same color profile?

We can not see if the examples from your client are in fact the PMS swatches, (or even 'screenshots'?) not the RGB. RGB and CMYK values are a approximation of the PMS. Nor do we know what your Colour settings (Colour profiles) are nor if you are having proof colours or Overprint on. Anyway: RGB values are just a approximation of the PMS...

Hi @Harribone100 , "Branding Guides" typically assume the profile for Hex/RGB values would be sRGB, make sure your document’s RGB Profile Assignment is set to sRGB. Pantone Solid Ink swatches are defined as Lab—a Lab color’s appearance is not affected by color profiles:

Thank you all. My document's profile was S RGB but the screen grab I took of the client's brand guide colours wasn't set to s RGB. Proof colours and overprint were both off. All good now:
