Matching Mortar Colour To Brick

[Mr Sparkle]

I have a large circular hole in my brickwork which I wish to fill with some colour matching mortar

I have uploaded an image of the brick work that I am trying to match

My question is, will any redish looking buildings sand work in this case or are there other ways to tint mortar?

Edit:

I may have found my answer... Powder Mortar Tone from Toolstation

Are there any other options?

Crushing up one of the bricks to dust with a hammer then making a paste with epoxy. Depends how large your hole is.
