XoCrazy

No more Theme switching and changing colors one by one!

Recolour Visual Studio while you watch.

Pick a colour. The editor repaints as you drag.
No OK button. No 400-row list. No "Default" where a colour should be.

The pitch

Visual Studio's Tools → Options → Fonts and Colors makes you guess. You scroll a few hundred alphabetical rows, click a colour, press OK, and only then find out what you did.

XoCrazy is a normal tool window that sits open beside your code. Change something and the code behind it changes. That's the whole idea.

What you get

🎨 Live. Drag the picker, watch if change colour in the file behind the window.

🎯 Stop scrolling. Put the caret on any token and press Ctrl+K, Ctrl+;. The window jumps straight to the thing that painted it.

🌈 40 themes built in. Dracula, Nord, Gruvbox, Monokai, Solarized, Catppuccin, Tokyo Night, One Dark, GitHub, Ayu, Rosé Pine, Everforest, Kanagawa and more. Hover a card and your actual code previews it. Cancel puts everything back.

🧩 Mix them. Syntax from one theme, background from another, margins from a third. Three independent slots, because liking Dracula's keywords doesn't mean liking its grey.

👁 Real colours, not "Default". Themed values are decoded to their actual RGB and shown with an inherited badge, so you always know what you're looking at.

💧 Proper picker. HSV field, hex box, screen eyedropper, harmony generator, recent colours, and a live WCAG contrast readout against the background actually behind the text.

↩️ Undo that works. Ctrl+Z per change, or Revert all to jump back to how things looked when you opened the window.

💾 It sticks. Your theme is saved and re-applied on restart — including for the items Visual Studio itself refuses to persist.
