Hi Evie, disease resistant in that basic color range to fit in with a more cottage garden theme:
Crepuscule (peachy-yellow noisette, shrub or climber)
Jude the Obscure (peachy-yellow, David Austin shrub or climber---amazing fragrance & healthy, BUT a stingy bloomer for me)
Mrs Oakley Fisher (single, apricot-gold HT)
Pink Gruss an Aachen (light pink, very double blooms, thornless, compact)
Molineux (lemon yellow, David Austin shrub, extremely floriferous)
If you want "exhibition style" hybrid teas for cutting:
Sunset Celebration (peachy-pink upright HT)
Tiffany (soft pink/yellow upright HT)
Compassion (peachy-pink/yellow, best as large freestanding shrub, but can be climber)
Winter Sunset (peach Buck upright shrub)
I've had success with all the roses listed here. All are fragrant & very disease resistant no spray (here, anyway.)
As you may already know, white roses can be tricky no spray. If you don't spray insecticides (I don't) thrips can ruin a lot of the lighter color blooms, & the damage is most visible with whites (the blooms get those icky brown edges.)
One last thought-if you're looking for a more cottage garden....for vertical interest do you already have tall bearded iris & salvia? And a perfect May-Oct blue blooming accent for your roses is Rozanne geranium. (I have a lot of part shade areas & have this plant everywhere, it really helps to tie the garden together.) If you don't mind pulling up the "volunteers," erigeron karvinskianus (aka fleabane, Santa Barbara daisy) is a great low mounding plant that is also very drought tolerant.
Best of luck! Dawn
