Counting coloured cells?

[Atomic]

I'd like to know how we can count coloured cells?

i.e

If cells A1 C1 E1 F1 and G1 are coloured, I’d like to know how I can see the
total coloured cells in H1?

I suppose it’s a little bit more complicated than it looks. Any help would
be appreciated. Thank you.
