Eye Color Genetics Predictor
A lightweight, high-performance web utility designed to help players of life-simulation games predict the potential eye colors of offspring. This tool is built as a single-file application, focusing on clean aesthetics and instant calculations.
Technical Specification
- Architecture: Single-file HTML (HTML5, Vanilla JS, CSS3).
- Frameworks: Tailwind CSS (via CDN) for styling. No build step or transpilation required.
- Storage: No
localStorage,sessionStorage, or cookies. State management is handled entirely in-memory using JavaScript variables. - Compatibility: Sandboxed iframe safe. No
alert(),prompt(), or external tracking.
Features
- Dual-Input Interface: Two drop-down menus or clickable visual swatches for selecting Parent 1 and Parent 2 eye colors.
- Instant Probability Engine: Real-time calculation using a probability matrix to output percentage-based results (e.g., 50% Blue, 50% Brown).
- Visual Output: Results are displayed in clean, modern cards with color-coded swatches representing each result.
- Reset Functionality: A single click clears inputs and results without page reloads.
- Responsive Grid: The UI uses CSS Flexbox/Grid to stack elements cleanly on mobile devices and expand nicely on wide screens.
UI/UX Design
- Aesthetic: Minimalist SaaS style. Sharp corners (or mild rounding), generous whitespace, and subtle box shadows.
- Palette:
- Background:
#FFFFFF(White) - Primary:
#3B82F6(Vibrant Blue for buttons) - Text:
#1F2937(Dark Gray) - Secondary Text:
#6B7280(Medium Gray) - Success/Result Cards:
#F9FAFBwith#E5E7EBborders.
- Background:
- Animations: Subtle
transitionproperties on buttons (hover states) and a fade-in animation for the results container when a calculation occurs.
Developer Directives
- Strict NO-Storage Rule: Do not use
window.localStorage. If you need to persist data during the session, use a simple variable in the global scope. - No Popups: Do not use
window.alert(). Use a hidden<div>modal that toggledisplay: nonetodisplay: flexwhen an error or informational message needs to be shown. - Accessibility: Ensure all input fields have clear
<label>tags and usearia-labelwhere visual labels are omitted. - Performance: Keep the entire script under 200 lines of code. Use a CDN for Tailwind CSS.

Frequently Asked Questions
Everything you need to know about using this application.
How does this eye color genetics calculator function?
This tool uses a probabilistic model designed to mirror common inheritance patterns found in popular life-simulation games. By inputting the primary eye colors of both parent characters, the application calculates the likelihood of various color outcomes for the offspring based on standard game engine randomization. The algorithm processes your inputs instantly within your browser, ensuring a seamless user experience. It assigns weighted probabilities to each potential eye color result, providing you with a clear percentage breakdown of what to expect when your characters expand their family.
Is this tool accurate for all character types?
The predictor is optimized for standard, base-game genetics logic commonly found in many life-simulation titles. It accounts for dominant and recessive trait behaviors typical in these game engines, making it a reliable reference for players looking to plan family lines or manage character traits. Please note that while the calculator provides accurate estimates based on common game logic, some variations may occur due to game-specific mutations or hidden genetic modifiers. It serves as an excellent planning aid for creating your ideal character generations.
Does the website save my personal data or simulation history?
We prioritize your privacy by keeping this tool entirely local to your device. The application does not utilize cookies, local storage, or server-side databases, meaning no information is stored, tracked, or shared when you use this calculator. Because the tool is strictly ephemeral, your input data is cleared immediately upon closing or refreshing your browser tab. You can enjoy a clean, private experience without worrying about data collection or persistent history files.
Can I use this on a mobile device?
Yes, this tool is designed with a fully responsive interface, ensuring it looks and functions perfectly on smartphones, tablets, and desktop computers. The UI adjusts dynamically to your screen size, providing a professional and clean experience regardless of the device you are using. Our commitment to a lightweight, single-file architecture means the tool loads rapidly, even on mobile data connections. You can easily keep this page open in your browser while playing your favorite simulation game to check genetic outcomes in real-time.
