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.
Every step runs locally — no account, no cloud upload, no internet required.
Includes:
• Tactile colour wheel with drag-to-select hue
• Six one-tap presets
• Adjustable hue range
• Real-time preview
• Before/after comparison
• Edit history
• Share via any app
Pro (one-time unlock):
• Batch — process up to 20 photos at once with the same settings
• Save to Photos at full original resolution
• Unlimited edit history
