Purple or Blue?

Happens to came across this blog post here. It is basically about 2 people arguing about colours.

josh524 claims that the "My Blog" as shown in this picture is purple.
cathyc claims that the "My Blog" as shown in this picture is blue.

If you do not want to read the details, you can scroll down to read the conclusion directly.

Alright if you choose to read on, let's now study this picture with the help of Adobe Photoshop's Colour Picker tool ...

In case you do not know what RGB value is, I shall briefly explain it here. It is represented in this format #RRGGBB where RR is the hexadecimal value representing the primary colour Red, GG for Green and BB for Blue.

The default blue have RGB value equal to #0000FF.
The RGB value for the blue as shown in that picture is #0000FE.

The default purple have RGB value equal to #800080.
The RGB value for the purple as shown in that picture is #871F78.

The default indigo have RGB value equal to #4B0082.
The RGB value for the indigo as shown in that picture is #2E0855.

The RGB value for the "My Blog" as shown in that picture is #1F224F

FYI: The so call default value here means I type in the colour names(eg. blue, purple, indigo, ...) in this website and then use Adobe Photoshop's Colour Picker tool to get the RGB value.

The definition of purple can be found in Wikipedia over here.
It says, "Purple is a general term for the range of shades of color occurring between red and blue. It is formed (in both subtractive pigment and additive light combinations) by mixing the primary colors red and blue in varying proportions, with possibly a very small quantity of the third primary color (green for light or yellow for pigment).
...
A difference in retinal sensitivity to red and blue light between individuals can cause further disagreement."

So that means as long as the G value is smaller than both the R value and the B value (G<R & G<B), then it can be generally be said to be purple colour. Whether or not it looks more towards red or blue will depends on each individual's retinal sensitivity.

So now let us break the "My Blog" colour down to its primary colour,
R = 1F (in Hexadecimal) = 31 (in Decimal)
G = 22 (in Hexadecimal) = 34 (in Decimal)
B = 4F (in Hexadecimal) = 79 (in Decimal)

The observation shows:
(G<R & G<B) is False. Therefore it cannot be said to be purple colour. So josh524's statement is proven to be False.
In addition, B is more than G is more than R (B>G>R). So Blue is the dominating primary colour in the "My Blog" colour. So cathyc's statement is proven to be True.

Conclusion:
josh524's statement saying that the "My Blog" as shown in this picture is purple is proven to be False.
cathyc's statement saying that the "My Blog" as shown in this picture is blue is proven to be True.
