v0.28 In development, coming soon
Spectra sets gamma, contrast, color and saturation for each screen on Windows, and adds a crosshair overlay. All of it lives in one glass app that restores your original colors when you quit.
Try it: drag the sliders or the comparison line. Switch between Tone, Color and Crosshair to explore the controls. Double-click a slider to reset it.
AI pictures are used as reference on this site, including inside these app screenshots. Real pictures are in the real app.
Live demo
Your browser only changes the picture below, while Spectra changes your whole display. Gamma, brightness, contrast and saturation use the app's math. Vibrance needs an NVIDIA card, and here it is an estimate.
The demo picture is AI-generated reference. Real pictures are in the real app.
Input brightness on the bottom, output on the side. The dashed line means no change.
Pricing
Secure checkout by Stripe. Your card details go directly to Stripe and never reach Spectra. Tax is included, and your receipt comes by email.
You need an account to buy, and your license goes on it. Windows 64-bit only.
Tuning
Tone and color sit on separate tabs, with a before and after view that updates while you drag. Close the window and Spectra keeps working from the tray. Quit it and your original colors come back.
Presets
Every preset shows its result on a picture that suits it, so you can see the difference before you click. Deleted a default by mistake? Restore defaults brings it back and leaves your own presets alone.
Crosshair
Pick a design and a color. The code below is a real Spectra share code, so a friend can paste it and get the same crosshair. Press Ctrl+Shift+X in the app to show or hide it.
The app adds sliders for ring, arm length, gap, thickness, dot, outline and opacity. It has room for 8 saved crosshairs, and color presets get share codes too.
Themes
Choose the accent color and how much the Geometry effect moves behind the glass. This page changes with you. In the app you also control fonts, corners, glow and your own background picture.

FAQ
Not yet. Spectra is still in development. Price and release date come later.
That depends on the game. Some games ban crosshair overlays or display filters in their rules, so check the rules for the games you play. Spectra doesn't bypass anti-cheat.
Spectra isn't code-signed yet, and new unsigned apps often trigger warnings. Signing is planned. Only download Spectra from this site or the official Discord.
Each account is tied to one PC so accounts can't be shared. If you change PC, log in there and choose Move to this PC. You can do that once every 7 days.
No. Turn Spectra off or quit it and your original colors return.
No. After the first install, Spectra tells you when an update is ready, installs it and restarts by itself.

When you log in, we store your email, your Discord user details if you use Discord, your license status, your PC's name, and a scrambled ID of your PC. We use them to run your account and enforce the one-PC limit. Passwords are stored scrambled by Supabase, and we can't read them. Your Spectra settings stay on your PC.
Our login and database run on Supabase. Payments are handled by Stripe, and we only keep the payment reference, never your card details. This site loads fonts from Google. You can ask us to delete your account at any time through our Discord.
When Spectra goes on sale, you can ask for a full refund within 14 days of buying. A refund ends the license on your account.
