I have found all sorts of code to convert from RGB to HSL, but seem to get
different results. I need to get the same results as the colour picker, so
when I feed in Red (255 or HFF0000) I want to get out Hue = 0, Saturation =
240 and Luninescence = 120.
The example below gives Luminance = 112
This is a sample

Hue As Integer
Saturation As Integer
Luminance As Integer

Blue As Integer

i've read about a few different ways of converting to b&w but none
seem to be 100%. i would like the flexibility to maybe only have the
sky in red, so what i was thinking is, decomposing an image to the
individual RGB channels. that would allow me to apply a mask on a
specific layer. the only "problem" i'm having is in regards to the
opacity of the layers. let's assume i would like to mix my chanels G
60% R 30% B 10%. if i apply these figures to the opacity slider (to
the layers after decomposing to RGB) the pictures remains "see thru".
then i thought the op...Convert from RGB (or HSI) to a defined colour like "RED" or "BLUE"...

What exactly do you mean? In what reasonable way can I distinguish
between RGB(0, 0, 100) and RGB(0, 0, 101)? Without a direct,
side-by-side comparison, it's impossible to even distinguish between
the two, and describing the ...How to convert RGB image to grayscale and convert it back to RGB again
Hi, I have question about converting image to grayscale and convert
back to its original type.I am having hard time figuring out how to
convert back the image that I've already converted to grayscale. Is
there any build in function in mathlab that can do that ? for instance
[X, cmap] = imread('Photo.jpg');
J = rgb2gray(X);
after i did all my operations on grayscaled image now how can I
convert it back?
Can anyone please help me
Did you happen to look at the help for rgb2gray and notice the mention
of ind2rgb at the bottom? That's the function you want to use...Converting day colours to night colours.
I have an application that is used on a ship that sails both day and night.
Because the bridge is dark at night the monitors are dimmed and all the
'day' colours are made a less bright. This to prevent the users from losing
their eyesight at early age.
Is there a formula for converting a bright colour to a less bright
counterpart and back?
The only restriction is that some contrast between seperate contrasting
colours must remain.

I'm having trouble with colour tranfer between RGB and CMYK. I've
tranferred several very colourful digital images from RGB>CMYK, but
when I view them in other applications (such as ACDSee and when I put
them into HMTL files for a website), the colour seems to revert to RGB
colours. Yet when I look at the same file in Phtoshop, the colours are
the CMYK colours.
I'm confused! Can anyone help?
