IsoluxPop one color, grey the rest

Isolux makes one colour pop while turning everything else to greyscale — in seconds, entirely on your device.

Pick a photo, drag the colour wheel to the hue you want to keep, and watch the selective colour effect appear in real time. Tap a preset (Red, Orange, Gold, Green, Sky, Purple) for instant results. Adjust the range slider to widen or narrow the preserved colour band. Toggle before/after to compare. Share directly to any app.

WHAT MAKES ISOLUX DIFFERENT

• Tactile colour wheel
  Drag around the wheel to pick exactly the hue you want to keep.
• Real-time preview
  The selective colour effect appears as you drag — there is no render step to wait through.
• Six one-tap presets
  Red, Orange, Gold, Green, Sky, and Purple are a single tap away.
• Adjustable hue range
  Widen or narrow the preserved colour band until only what you meant stays in colour.
• Before/after and instant sharing
  Toggle the comparison to check your work, keep an edit history, and share straight to any app.
• Fully offline
  Every step runs locally — no account, no cloud upload, no internet required.

WHO IS ISOLUX FOR?

• Photographers who want one subject to carry the whole frame
• Anyone making a poster, cover, or post that needs a single accent colour
• People who want the look in seconds rather than in a layered editor
• Privacy-minded users who would rather their photos stayed on the device
