Convert colors between HEX, RGB, and HSL formats

Digital colors can be represented in several formats: HEX uses hexadecimal codes (#FF0000), RGB uses red-green-blue values (255,0,0), and HSL describes hue-saturation-lightness (0,100%,50%). Each format serves different purposes in design and development.

Understanding Color Formats

Understanding color formats enables effective color manipulation. For example, to create a lighter version of a color in HSL, you can adjust the lightness value while keeping hue and saturation constant.

Color Manipulation

HEX codes are commonly used in CSS and design tools. RGB is intuitive for color mixing and digital displays. HSL is particularly useful for creating color variations as it matches how humans perceive color relationships.

A percentage expresses a value as parts per hundred, making it easier to understand proportions and comparisons. The % symbol represents this relationship - for example, 75% means 75 parts out of 100. This universal mathematical concept helps us express everything from academic grades to financial calculations in a standardized way.

What is a percentage?

Percentages are essential tools in daily life, from calculating tips and discounts to understanding interest rates and investment returns. They help us make informed decisions about budgets, analyze business performance, track progress toward goals, and compare different quantities in a meaningful way.

Why percentages matter?

To find a percentage, divide your target number by the total and multiply by 100. For instance, to find what percentage 15 is of 60: divide 15 by 60 (0.25) and multiply by 100, giving you 25%. For percentage change, subtract the old value from the new value, divide by the old value, and multiply by 100.

Calculate optimal bedtime or wake-up time based on sleep cycles. Use our sleep calculator to find the best time to go to bed or wake up based on sleep cycles. Get better sleep quality with optimal sleep cycle planning.

Sleep cycles are the natural patterns of sleep that our bodies go through each night. A complete sleep cycle includes light sleep, deep sleep, and REM sleep, and typically lasts about 90 minutes. Waking up at the end of a cycle rather than in the middle can help you feel more refreshed.

Understanding Sleep Cycles

If you need to wake up at 6:00 AM, you might aim to fall asleep at either 8:30 PM (for 6 cycles/9 hours), 10:00 PM (for 5 cycles/7.5 hours), or 11:30 PM (for 4 cycles/6 hours), depending on your sleep needs.

Sleep Cycle Planning

Planning your sleep around complete cycles can improve sleep quality, increase morning alertness, reduce grogginess, and enhance overall cognitive function. It's particularly helpful for people with irregular schedules or those who struggle with insomnia or sleep quality issues.
