Corallina officinalis
This seaweed has a feathery appearance with its regular, opposing branched pattern. It varies in colour due to age and lighting conditions. The deeper it is it grows dark pink. It has a pink, disc-shaped encrusting holdfast which helps it anchor itself to rocks, shells or other larger seaweeds. It can grow up to 12cm in height.
It is typically found lining the edges of mid-shore rock pools. It is common and widespread.

I expected a little more reddish color? Does it differ depending on where it grows? How deep it is?

Yes, it tends to be paler in shallower rock pools, like the one I found it in, but a deeper pink in deeper water.
