Rookie mortar colour question

[copea]

Morning, I'm hoping someone can help out with this basic question?

I need to repoint a small area of brickwork on my Victorian house.
No matter what I've tried, all the mortar mixes I've made up are too grey.
I've been using regular grey cement and builder's sand from Wickes.

The colour I'm aiming for is more golden.

Example:

Is there a way of achieving this or very similar without sending off a sample and getting a mix custom made?

You need yellow sand not red.

Haha! Well that was pretty obvious, on reflection.
Thanks!
I take it a proper builder's merchant will stock it, as Wickes don't?
