```scheme
(use-modules (webview)
(htmlprag)
(ice-9 receive)
((language guilescript compile) #:prefix gs:))
(define js-script
(receive (js _)
(gs:compile
'(begin
(define (calcloop)
(let ((date (js-new Date))
(hour (js-invoke date getHours))
(min (js-invoke date getMinutes))
(sec (js-invoke date getSeconds))
(toHex (lambda (d)
(define hex (js-invoke (js-invoke (+ "0" (js-invoke (Number d) toString 16)) slice -2) toUpperCase))
hex))
(hex (+ "#" (toHex hour) (toHex min) (toHex sec))))
(js-set! (js-invoke document getElementById "clock") innerHTML (+ hour ":" min ":" sec))
(js-set! (js-invoke document getElementById "clock-hex") innerHTML hex)
(js-set! document.body.style background hex)))
(js-set! window onload (lambda ()
(setInterval calcloop 1000)))))
js))
(define page-html
(sxml->html `(body (@ (style "display:flex; flex-direction:column; justify-content:center; align-items:center"))
(h1 (@ (id "clock")
(style "color: #fff")) "")
(h2 (@ (id "clock-hex")
(style "color: #fff")) "")
(script ,js-script))))
(define wv (webview-create 1 (make-webview-t)))
(webview-set-title wv "Clock")
(webview-set-html wv page-html)
(webview-set-size wv 250 250 0)
(webview-run wv)
