Small web tools made alongside the music. They open in the browser on a phone or laptop, with nothing to install. Interfaces are in Korean.

Palette Lab
Colour to sound, web app
Pulls five colours from a photo, then turns them into Suno prompt keywords and a moving media-art piece. Everything runs in your browser; photos are never uploaded.

Clarinet Transposer
클라리넷 이조기 · Transposition, web app
Rewrites solfège (계이름) text or MusicXML files for B♭, A, E♭ and bass clarinet, drawing the transposed staff notation. Works both ways, so clarinet parts can be read back into sounding pitch too.

Hearing the Clarinet in Colour
색으로 듣는 클라리넷 · Sound to colour, web app
A microphone or a recording drives a colour field and an electronic layer. Palettes come from photos or Palette Lab HEX codes, and the app learns which sound belongs to which colour.

제주 풍경 색 보정 · Photo colour restoration, web app
Restores the colour in hazy landscape photos, shown as a before-and-after split you can drag, and extracts the palette as HEX, CSV or JSON. Everything runs in your browser.
