If you are OK with preprocessing the argument list into a dictionary, then
you can use keyword-apply/dict
<https://docs.racket-lang.org/reference/dicts.html?q=keyword%2Fapply#%28def._%28%28lib._racket%2Fdict..rkt%29._keyword-apply%2Fdict%29%29>
.
For example:
#lang racket
(require racket/dict)
(define proc (lambda (#:color color #:size size) (display (cons color size))))
(define args '(#:color "red" #:size 3))
(define args*
(for/hash ([chunk (in-slice 2 args)])
(values (first chunk) (second chunk))))
(keyword-apply/dict proc args* '())
