Real-time road grade with Tour de France-style color zones, right on your Garmin Edge.

Grade with Color shows the current uphill grade (%) in large, easy-to-read digits and colors the number by difficulty zone — yellow (easy climb), orange (moderate), red (steep), purple (very steep). Downhill shows a neutral color so you know instantly when the road flips.

WHY IT'S BETTER:
• Responsive grade — uses a Kalman filter on the barometer altitude to estimate vertical speed and compute grade = vertical speed / horizontal speed. It reacts faster than simple distance-window calculations and stays stable.
• Adjustable smoothing — three presets (Fast / Balanced / Smooth) tune response vs stability to match how you ride.
• Custom zone thresholds — set the % boundaries for the 4 uphill color zones and the climb "start" threshold.
• Current altitude — small readout in the corner so you always know your elevation.
• Theme-aware — auto switches between light (day) and black (night) backgrounds following your device color theme.

USES:
• Ride climbs and see at a glance whether you are on an easy 4% or a brutal 10%+.
• Pace yourself on long mountain stages — the color tells you when to ease off before it hurts.
• Quick altitude reference without a dedicated field.

FEATURES:
• Large digits with unit (%), bottom-aligned baseline.
• 4 uphill color zones (default 3/6/9/13%, all adjustable).
• Downhill / flat shown in neutral color; only uphill gets color.
• Metric and imperial altitude (m / ft) follows device units.
• Low battery impact — runs once per second.

COMPATIBILITY:
• Edge 540 / 840 / MTB / 1040 / 550 / 850 / 1050.

GradeWithColor

实时道路坡度 + 环法配色难度分区，显示在你的 Garmin Edge 码表上。

Grade with Color 用超大数字实时显示当前上坡坡度(%)，并按难度分区给数字上色：黄（缓坡）、橙（中等）、红（陡坡）、紫（极陡）。下坡显示中性色，一眼分辨道路方向翻转。

更强的地方：
• 响应更快的坡度 —— 用卡尔曼滤波处理气压计海拔，估计垂直速度，坡度 = 垂直速度/水平速度，比简单距离窗口计算反应更快且更稳定。
• 平滑度可调 —— 快速/平衡/平滑三档，调节响应速度与稳定性。
• 分区阈值可自定义 —— 可调 4 档上坡变色边界和"起步"阈值。
• 当前海拔 —— 角落小字显示当前海拔。
• 主题自适应 —— 跟随码表日夜主题自动切换浅色/黑色背景。

兼容：Edge 540 / 840 / MTB / 1040 / 550 / 850 / 1050。
