Ausgehend von drei Zahlenwerten - den roten, grünen und blauen Elementen einer Farbe (acht Bits pro Kanal, 0 bis 255) - muss Ihr Programm den Namen ausgeben der angegebenen Farbe .

Zum Beispiel;

Input:  255, 0, 0  
Output: Red

oder;

Input:  80, 0, 0
Output: Dark Red

Dies ist ein Beliebtheitswettbewerb, also gewinnt jede Antwort, die die meisten Stimmen bis zum 1. Juli hat.

Python

Dies ist ein Python-Skript, das die Ergebnisse der xkcd- Farbumfrage verwendet , in der Randall Munroe Tausenden von Menschen genau dieselbe Frage gestellt hat. Er kam zu folgender Karte:

Die Umfrage enthält nur Daten zu vollständig gesättigten Farben (ich denke, nicht gesättigte Farben würden alle als "gräulich" bezeichnet). Dies bedeutet, dass wir einige farbbezogene Tricks ausführen müssen, um die vollständige Sättigung unserer Eingabe zu erzwingen.

Was ich hier gemacht habe, ist einfach die Eingangsfarbe in HSV umzuwandeln, die Sättigung anzukurbeln und es einen Tag zu nennen. Dies ist aus Sicht der Farbwahrnehmung wahrscheinlich nicht sehr korrekt, funktioniert aber hier gut genug - und es ist einfach genug, dass Sie nur die Standardbibliothek benötigen. Batterien in der Tat enthalten.

Das Skript erwartet, dass sich satfaces.txt von hier ( Spiegel ) im aktuellen Verzeichnis befindet.

import sys, colorsys

n = (int(sys.argv[1], 16))
r = ((n & 0xff0000) >> 16) / 255.0
g = ((n & 0x00ff00) >> 8) / 255.0
b = ((n & 0x0000ff)) / 255.0

(h, s, v) = colorsys.rgb_to_hsv(r, g, b)
(r, g, b) = colorsys.hsv_to_rgb(h, 1, v)

match = "[{}, {}, {}]".format(int(r*255), int(g*255), int(b*255))

for line in open("satfaces.txt"):
    if line.startswith(match):
        print("You were thinking of: " + line.split("] ")[1].strip())
        break

Einige Beispielläufe:

$ python color.py CEB301
You were thinking of: yellow
$ python color.py CC9900
You were thinking of: orange
$ python color.py CC0000
You were thinking of: red
$ python color.py 0077FF
You were thinking of: blue

Und hier sind die Farben:

Ich würde sagen, das ist ziemlich nah.

Update mit GUI!

Die Farbliste entnehme ich dieser Wikipedia-Seite (und den dazugehörigen Seiten).

Ich habe auch einige NLG hinzugefügt, um Ergebnisse wie "Bulgarische Rose mit etwas weniger Grün und Blau" und einige Varianten davon zu erzielen. Versuchen Sie mitzuspielen, um zu sehen, ob Sie anhand dieser Rückmeldungen die wahre "bulgarische Rose" erraten können. :)

Der Algorithmus versucht, die Farbe zu finden, die der Eingabe am nächsten kommt, wie durch den euklidischen Abstand definiert. Sie können also ein beliebiges Zahlentriplett eingeben und es wird die Farbe angezeigt, die dem Triplett am nächsten kommt.

(Der Code akzeptiert "durch Kommas getrennte", "durch Leerzeichen getrennte" oder "durch Kommas getrennte" Werte.)

Warnung

Dieser Code stellt eine Verbindung zu Wikipedia her und erfordert daher eine Internetverbindung, um das erste Mal ausgeführt zu werden (und die Informationen in eine Datei im selben Wörterbuch zu schreiben). In den folgenden Fällen wird jedoch aus der Datei gelesen. Wenn Sie die Offline-Version möchten, finden Sie den Code unter diesem Ideone-Link (mit Beispiellauf).

Für die raffinierteren Hunde da draußen:

function getColorName(r, g, b) {
    var gray = (0.21*r + 0.71*g + 0.07*b);
    if (gray < 64)
        return "black";

Mathematica

Update: Es wurde ein Parameter hinzugefügt, mit dem die Anzahl der Farben festgelegt werden kann, die am nächsten angezeigt werden sollen. Die Standardeinstellung ist 5 Farben.

Ausgehend von den RGB-Werten einer unbenannten Farbe werden im Folgenden die nnächsten Farben aus einer Liste von 140 HTML-Farbnamen ermittelt. Anschließend werden die unbenannte Farbe und die 5 nächsten Nachbarn in einem 3-Feld mit Achsen für Rot, Grün und Blau dargestellt. In der Plotbezeichnung wird die nächstgelegene Farbe benannt und die RGB-Werte angegeben.

colorInterpret[rgb_,n_: 5]:=
Module[{colorData,valsRGB,pts,closest},
colorData=({ColorData["HTML",#],#}&/@ColorData["HTML","Range"][[1]])/.{RGBColor[x__]:> {x}};
valsRGB=colorData[[All,1]];
pts=Append[colorData[[Position[valsRGB,#]&/@Nearest[valsRGB,rgb,n]//Flatten]],{rgb,"Unnamed Color"}];
closest=pts[[1]];
Graphics3D[{PointSize[.05],
{RGBColor@@#,Point[#],Text[Style[#2,Black,14],(#-{.01,.01,.01})]}&@@@pts
},
Axes-> True,
PlotLabel-> Row[{"closest color: ", closest}],
ImageSize-> 600,
ImagePadding-> 50,
BaseStyle-> 14,
AxesLabel->{Style["Red",18],Style["Green",18],Style["Blue",18]}]]

Beispiele

Zeigen Sie die 5 nächsten Farben an:

 colorInterpret[{.55, .86, .69}]

Zeigen Sie die 15 nächsten Farben an:

CJam

l~]:X;"xkcd.com/color/rgb.txt"gN%"  "f%{[1=1>eu2/{:~Gb}%X]z{:-}%2f#:+}$0=0=

Dadurch wird die Liste der Farben von xkcd abgerufen und die nächstgelegene gefunden.

R

R hat eine eingebettete Liste mit 657 Farbnamen für Plotzwecke. Der folgende Code nimmt Eingaben vom Benutzer entgegen, berechnet den Abstand zwischen dieser RGB-Eingabe und dem RGB-Wert dieser 657 Farben und gibt den Namen der nächstgelegenen aus.

a=as.integer(strsplit(readline(),", ")[[1]]);color_list=sapply(colors(),col2rgb);names(which.min(colSums(abs(apply(color_list,2,function(x)x-a)))))

Ungolfed:

a <- as.integer(strsplit(readline(),", ")[[1]]) #Ask user input as stdin, and process it
color_list <- sapply(colors(),col2rgb) #Convert the color name list into an RGB matrix
#Computes the difference with user input, adds the absolute value and output the name of the element with the minimal value
names(which.min(colSums(abs(apply(color_list, 2, function(x)x-a)))))

Beispiele:

> a=as.integer(strsplit(readline(),", ")[[1]]);color_list=sapply(colors(),col2rgb);names(which.min(colSums(abs(apply(color_list,2,function(x)x-a)))))
80, 0, 2
[1] "darkred"
> a=as.integer(strsplit(readline(),", ")[[1]]);color_list=sapply(colors(),col2rgb);names(which.min(colSums(abs(apply(color_list,2,function(x)x-a)))))
150, 150, 150
[1] "gray59"
> a=as.integer(strsplit(readline(),", ")[[1]]);color_list=sapply(colors(),col2rgb);names(which.min(colSums(abs(apply(color_list,2,function(x)x-a)))))
0, 200, 255

> a=as.integer(strsplit(readline(),", ")[[1]]);color_list=sapply(colors(),col2rgb);names(which.min(colSums(abs(apply(color_list,2,function(x)x-a)))))
255, 100, 70
[1] "tomato"

Bearbeiten: Gleiche Idee, aber unter Verwendung der Namensliste von colorHexa :

a=strsplit(xpathSApply(htmlParse("http://www.colorhexa.com/color-names"),"//li",xmlValue),"#")
n=sapply(a,`[`,1)
r=apply(do.call(rbind,strsplit(sapply(a,`[`,2)," "))[,2:4],2,as.integer)
n[which.min(colSums(abs(apply(r,1,`-`,as.integer(strsplit(readline(),", ")[[1]])))))]

Beispiel:

> a=strsplit(xpathSApply(htmlParse("http://www.colorhexa.com/color-names"),"//li",xmlValue),"#")
> n=sapply(a,`[`,1)
> r=apply(do.call(rbind,strsplit(sapply(a,`[`,2)," "))[,2:4],2,as.integer)
> n[which.min(colSums(abs(apply(r,1,`-`,as.integer(strsplit(readline(),", ")[[1]])))))]

Mein Versuch - die Mörderfunktion ist, dass es keine Internetverbindung erfordert!

Pharo Smalltalk

Legen Sie dies in einen Pharo Workspace und drucken Sie es aus .

| color colorNames nearestColorName |
color := Color r: 255 g: 0 b: 0 range: 255.
colorNames := Color registeredColorNames copyWithout: #transparent.
nearestColorName := colorNames detectMin: [ :each | (Color named: each) diff: color].

Die Ergebnisse sind von unterschiedlicher Qualität. Alle dunkleren Farben werden als grau , dunkelgrau oder sehr dunkelgrau bezeichnet . Wahrscheinlich Color'sdiff: Methode könnte besser sein.

Für eine sehr einfache Visualisierung machen Sie :

((Morph newBounds: (0@0 extent: 200@200 ) color: color) addMorph: nearestColorName asMorph) openInWorld.
