It could be interesting to document color resources in README, and give some philosophy around this project.

For example, http://www.thisiscolossal.com/2014/05/color-book/ is fascinating.

http://goffgrafix.com/pantone-rgb-100.php

https://github.com/VAlexander/Chameleon has some good concepts, notably structured color schemes and some flatifying methods.

There're several Winsor-Newton charts:

Winton Oil Colour
Griffin Alkyd Fast Drying Oil Colour
Artisan Water Mixable Oil Colour Artists' Oilbar

The colors have other information, such as Colour name, Colour code, Permanence Rating, Opacity and the ASTM rating.

/Users/erick/iOSProjects/xxx/Pods/EDColor/EDColor/UIColor+Hex.m:67:25: Implicit conversion loses integer precision: 'unsigned long long' to 'int'

Force type cast to int looks like solve this problem.

// xx
            r = g = b = (int) value;
            a = 255;
            break;

We're trying to use the darken: method, but an updated version for this library has not been created since they method was written.

Awesome library btw

Note the British spelling of colour, not sure what to do about that.

UIColor+HSB.h is missing a newline at the end of the file. Creates an annoying warning (obviously, no functional problems).

Kinda not worth forking to PR this one... ;)

Currently I'm short on time, but I'll add my X11 colors (https://github.com/steffex/x11Colors) library to this one!

https://en.wikipedia.org/wiki/HWB_color_model

HWB is a cylindrical-coordinate representation of points in an RGB color model, similar to HSL and HSV.

I think the Github repo should be called EDColor to match.

This might be a bit crazy, but how about adding a UIColour class that delegates all calls to UIColor?

This is brilliant: http://www.checkman.io/please/

Any interest in replacing OCUnit with Specta / Expecta? It would be an upgrade with better syntax IMO.

[UIColor colorWithHexString:@"#CCC" andAlpha:0.5f];
Please add this helpful feature.

Receiving a UIColor+HSB.h:15:5: No newline at end of file. The compiler flags for no newline at end of file [-Werror,-Wnewline-eof].

Using Cocoapods with Using EDColor (1.0.0).

Dan Colen creates mixed-media, sculptural, and painted works that locate interest and magic within the seemingly ordinary and undervalued.

A recent post includes his color palette, that has some interesting names like "Emerald City" or "Swamp Thing". Check out https://artsy.net/post/marinakcashdan-bird-sh-star-t-bubble-gum-and-crack-pipes.

It's not a huge deal, but colorWithHexString is slow. I was considering switch to EDColor and I benchmarked my existing fromHex and colorWithHexString. Here are the results on an iPad 2:

    const int ITER = 10000;
    double tm = CACurrentMediaTime();
    for (int i = 0; i < ITER; ++i) {
        [UIColor fromHex:@"#123456"];
    }
    NSLog(@"fromHex %.3f", CACurrentMediaTime() - tm);
    tm = CACurrentMediaTime();
    for (int i = 0; i < ITER; ++i) {
        [UIColor colorWithHexString:@"#123456"];
    }
    NSLog(@"colorWithHexString %.3f", CACurrentMediaTime() - tm);

fromHex 0.070
colorWithHexString 2.170

This makes me a bit nervous about using colorWithHexString in paint-intensive code, at least not without some caching. Here's the fromHex that I'm using:

+ (UIColor *)fromHex:(NSString *)hex
{
    const char *s = [hex cStringUsingEncoding:NSASCIIStringEncoding];
    if (*s == '#') {
        ++s;
    }
    unsigned long long value = strtoll(s, nil, 16);
    int r, g, b, a;
    switch (strlen(s)) {
        case 3:
            // RGB
            r = ((value & 0xf00) >> 8);
            g = ((value & 0x0f0) >> 4);
            b = ((value & 0x00f) >> 0);
            r = r * 16 + r;
            g = g * 16 + g;
            b = b * 16 + b;
            a = 255;
            break;
        case 6:
            // RRGGBB
            r = (value & 0xff0000) >> 16;
            g = (value & 0x00ff00) >>  8;
            b = (value & 0x0000ff) >>  0;
            a = 255;
            break;
        default:
            // RRGGBBAA
            r = (value & 0xff000000) >> 24;
            g = (value & 0x00ff0000) >> 16;
            b = (value & 0x0000ff00) >>  8;
            a = (value & 0x000000ff) >>  0;
            break;
    }
    return [UIColor colorWithRed:r/255.0f green:g/255.0f blue:b/255.0f alpha:a/255.0f];
}

Thanks for all your hard work!
