Suppose a segmented control's tint color is set to RGB(69, 175, 225) but the actually color from color picker range from (top most) RGB(146, 181, 211) to (bottom most) RGB(82, 118, 147).
So how can I expect the actually displayed color of the segmented control. For example, if I want the color of the bottom most point is RGB(69, 175, 225), what is the RGB value should I set?
The tint is a color on which some fancy visual effects (glossy reflections and so on) is applied. iOS applies them to app icons, tab bars, navigation bars and many other things. I think it would be wrong for you to make any assumptions as to what the local color for a given pixel is for a given tint, given these visual effects vary from UIElement to UIElement and probably from one OS version to another.

Human Interface Guidelines, "Color" section talks about the using system color is preferred. There are color codes for all system colors however for the foreground content text color there only APIs provided.
So what exactly is the color code for labels in both light and dark mode? Our designers need these colors for their mockup.

The color code fetched from the Playground does not seem right. The hex codes are all the same.
The RGB values of secondary, tertiary, and quaternary label colour are in fact the same. They only differ in the alpha value, which you might have forgotten about :)
From what I observed:
Label colour has 100% alpha
Secondary label colour has 60% alpha
Tertiary label colour has 30% alpha
Quaternary label colour has 18% alpha
Here's another way to find the hex value of a system colour. Go to the asset catalog of an Xcode project. Add a colour set:
Then, select "Any Appearance" or "Dark Appearance" depending on which one you want ("Any Apperance" means "not dark"). You can even check the "High Contrast" box to have more options for how your dynamic colour will look depending on the situation.
Then select your desired colour from the "Content" dropdown (see freehand circle).
Finally, you can click on "Show Color Panel" to see the hex:
Is there any way to skip a particular color in whole app when device is in smart invert mode of accessibility?
I don't want the blue color in my app to be inverted. I have am image which have black and blue color text in it. I want the black color text to be inverted but want to skip blue color.
Any help would be appreciated.
P.S -I am familiar with accessibilityIgnoresInvertColors. But this property can be applied on uiview or object but i need to skip a color.
do it inside the appcolor constant file :- you can check UIAccessibilityIsInvertColorsEnabled() if its true then return clear color else reurn the blue color.
I want my UILabel's text color to be dependent on the UIImage that is beneath it. I think the solution involves getting the average color of my UIImage but I don't know what tools are available for me in swift to get that information. Also, my label is in the top left corner. I don't want the average color of the whole image. I want the average color of the area around my label.
I created a UIView with a set background color. Lets say RGB value 185, 45, 42. For some reason, when I take a screenshot of this view, it is not that color. It is a little bit darker. Is there a reason why UIView would do this?
The UIView background color is set in interface builder like this:
When I run it on the simulator and take a screenshot and use the eye drop tool to determine the color, the numbers that show up are a little bit darker than what I entered. Same with a button.
I have other screens with the same red color and the screenshot I take of those, the red actually comes out correctly. I've been trying to determine what the difference is between those screens, but so far have not seen any. So I was just wondering if anyone would have any knowledge of anything that "could" case such a color change.
A common mistake when setting a color numerically in Interface Builder is to neglect the color space:
Different color spaces will give different colors (visually) for the same RGB values.
When you set RGB color, you should notice that all the three color values range from 0 to 1, so give them a value greater than 1 would never work. Try this:
RGB(185 / 255.0, 45 / 255.0, 42 / 255.0)
I have a colour (42, 61, 68) with HEX Colour # 2A3D44, which I set it in UIView's background colour property in the xib.
I have compared the results with colour meter and it's not what I expected, the colour I got is (32, 47, 51). You can take a look at it yourself here.
Any ideas?

Guys my mistake I didn't selected the Generic RGB from the colour dialog.
