What colour is this “gold” Apple Watch?

I previously bought my wife a Gold iPhone 11 and for her birthday this year, I bought her a Gold Apple Watch Series 6. When it arrive, the order clearly stated 40mm Apple Watch Series 6 Aluminium in Gold with Cypress Green strap. When we opened it, it was more like a ‘pink’ colour – it is definitely not the same colour as her phone:

The picture shows (from the left to the right):

• my Apple Watch Series 6 Nike Edition in Aluminium Silver
• my wife’s old Apple Watch Series 2 in Aluminium Gold with Blue Strap
• the new watch we received

We called Apple Store Support and had a quite strange conversation about whether this was a manufacturing fault or by-design, so were left unsure as to how we should proceed.

Please can someone with some experience in these things tell us what colour this is / is it correct?
