Yellow shrubs I like are hypericum hidcote ..bright yellow flowers all summer...Potentillas which have pale, mid and elbow yellow flowers. Coronilla glauca has yellow flowers often throughout the year. Mahonias for winter yellow flowers. Yellow dahlias,,rudbekias, argyranthemums, yellow hemerocallis,etc....there are masses of,yellow flowerimg plants.
In between, to set off these yellow flowers, blue shrubs like caryopteris, ceratostigma, ceanothus,lavendars, and blue perennials like aster little Carlow and frikartii monch, blue agastaches, blue hardy geraniums, blue lupins,delphiniums, etc. I would add orange flowers too (for yellow,,blue amd orange scheme) like geum Totally Tangerine, echinacea Marmalade, orange gazanias, heleniums like moerheim beauty, and the like.
Some evergreen yellow shrubs like choisya sundance, yellow grasses like Bowles golden grass and low yellow mounds like campanula dicksons gold (which has blue flowers atop evergreen mounds)
A yellow andBblue border with dots of orange would look great
