CornflowerBlue
A mid, cool indigo -- the dependable foundation of trustworthy interfaces.
Create CornflowerBlue in PHP
Parse the catalog’s canonical value once, then keep the resulting color object throughout the rest of your code.
<?php
use PhpColor\Color\Color;
$cornflowerblue = Color::parse('#6495ED');ColorInterface
$cornflowerblue
#6495ed · oklch(0.6746 0.1414 261.3)
Build a CornflowerBlue harmony
tetradic() keeps CornflowerBlue and adds three partners at equal quarter-turns around the OKLCH hue wheel.
<?php
$harmony = $cornflowerblue->tetradic();
foreach ($harmony as $color) {
echo $color->toHex().PHP_EOL;
}- 0
#6495ed - 1
#d66fa1 - 2
#c28c00 - 3
#00b28b
Generate a CornflowerBlue scale
Keep the original hue and chroma, then vary OKLCH lightness to produce perceptually ordered steps.
<?php
$oklch = $cornflowerblue->to('oklch');
foreach ([0.97, 0.92, 0.84, 0.74, 0.66, 0.58, 0.48, 0.40, 0.32, 0.24, 0.16] as $lightness) {
$step = $oklch->withChannel('l', $lightness);

Format CornflowerBlue for the web
The same object can emit a compact Hex value, an sRGB CSS function, or its perceptual OKLCH coordinates.
<?php
$hex = $cornflowerblue->toHex();
$rgb = $cornflowerblue->toCss('srgb');
$oklch = $cornflowerblue->to('oklch')->toCss();- hex
#6495ed- rgb
rgb(100 149 237)- oklch
