When you have to determine colours it becomes quite complicated after a while. The difficulty starts when you have to identify a colour that comes from natural sources. Perception is often undefinable and depends on adjacent colours.
You would not believe how differential people react to a colour and how they would define it. What is still orange and what is already red, or still yellow? Also it is difficult to find pure colour in natural environments - but let's start with the "easier" ones: the colour codes of the electronic medium - the computer or rather the codes of the HTML language.
The colour range for the orange (in HTML definition) merely consists only of 3 colours - the 4rth does not belong (or rather supported by description) officially to the oranges as you can see from the name:
And here it starts already. Depending on your monitor and its settings these colours will appear differently on your computer.
It is in fact a different hue although at first glance it seems to belong to the same range! But you can check this by looking at your monitor from different angles. Now you see why the determination of a colour is so difficult.
Here is a nice chart of the Basic Oranges:
|CC6600||204,102,0||2||Sienna / Orange - brown|
|663300||102,51,0||3||Dark Chocolate Brown|
|CC6633||204,102,51||8||Brick / Red-brown|
Now let us find the codes for the following images:
The colour codes are:
You see - not a single image contains the pure colour code of orange - all images contain different hues of orange.
