Tall perennials similar to helianthus and rudbeckia

Hi, does anyone know/can recommend any tall, later flowering perennials that are similar to rudbeckia or helianthus but not yellow. I have helianthus salicifolius which does really well here, most years, and rudbeckia herbstonne which I've planted this year but would like similar plants with a different colour to do their job in other areas. I have smaller eupatoriums dotted about so don't want to go that root and would prefer something with a similar sizes flower to the helianthus/rudbeckia (although not necessary) as it will need to stand out from a couple of metres. I grow annual sunflowers, mostly dark reds and chocolates, which fill that void at the moment but I'd like to move away from annuals to save some water going forward. The garden just turns yellow this time of year with golden rods, achillea cloth of gold and the two already mentioned dominating.

So generally I'd like something maybe 4-6ft thats perennial, will do well in free draining, relatively poor soil,  and flowers from now onwards.

    Maybe Asters would suit, they come in white pink and purple.

    Shasta daisies?  Tall with white flowers so a good contrast and visible from afar.

    Inula magnifica.

    Leucanthemella serotina? A taller version of ox-eye daisy, although it seems to prefer moist soil.

    Helenium Moerheim Beauty is red/rusty brown and would tone well with the reds/chocolates or tall dahlias, gladioli, aconitum etc., might get you close to 4ft but not 6.

    Echinaceas would’ve been ideal in free-draining soil re flower size and popping colour range but most probably too small - the only really tall one I can think of is yellow!

    More towards the 4ft end, but Echinacea pallida and Aster cordifolius 'Little Carlow'. Aster umbellatus is a really nice natural looking white one, and you'll soon have plenty to give away to friends :) Aster 'Violetta' is purple, about 5ft.

    Sanguisorba tenuifolia 'Alba' is tall, white, late flowering - but not daisy-like. Verbena bonariensis isn't daisy like either, but is tall and indispensable.

    I have chicory (Chicorium intybus) in flower at the moment, a nice clear blue and maybe 6-7 feet tall, taller than my Helianthus Lemon Queen, although it does need staking.
    If you don't need the flowers to be daisy-shaped, some of the agastaches are tall, Blackadder is about 5 feet for me, and so is a white one from seed that I don't know the name of. Joe Pye weed, Eupatorium is another possibility (pink), and the taller Salvias Amistad, Amante and S. guaranitica if you don't get waterlogged or extremely cold in winter. I also have Verbena hastata "pink spires" flowering at about 5 feet tall.
    Aster "Little Carlow" is shorter for me, about 3 feet.

    No, I'm open to anything just used those as an example because they are substantial but manageable if you get what I mean. I have verbena, fennel and a few other tall but wafty plants but I tend to mix them through the border rather than at the back. It basically something that provides a backdrop to the other plants like a hedge would but that is easy to divide and keep tamed.
