you want an interpolation between the first and the second colour. Interpolating colours is easy by calculating the same interpolation for each of its components (R, G, B). There are many ways to interpolate. The easiest is to use linear interpolation: just take percentage p of the first colour and percentage 1 – p of … Read more
iOS 17/ macOS 14 (advanced but native) You can ask for resolving Color components in the given environment, because colors are different in different environments (for example in dark and light environments). In the following sample, I resolved it using the current environment of the used color. struct ContentView: View { @Environment(\.self) var environment @State … Read more
I am the author of the second implementation. It has always behaved correctly for me, but you wrote 2.9 / 6.9 instead of 2.0 / 6.0. Since you target GLSL, you should use conversion routines that are written with the GPU in mind: // All components are in the range [0…1], including hue. vec3 rgb2hsv(vec3 … Read more
The fourth layer is the transparency value for image formats that support transparency, like PNG. If you remove the 4th value it’ll be a correct RGB image without transparency. EDIT: Example: >>> import PIL.Image >>> image = PIL.Image.open(‘../test.png’) >>> import numpy as np >>> image = np.array(image) >>> image.shape (381, 538, 4) >>> image[…,:3].shape (381, … Read more
try this out: var rgbString = “rgb(0, 70, 255)”; // get this in whatever way. var parts = rgbString.match(/^rgb\((\d+),\s*(\d+),\s*(\d+)\)$/); // parts now should be [“rgb(0, 70, 255”, “0”, “70”, “255”] delete (parts[0]); for (var i = 1; i <= 3; ++i) { parts[i] = parseInt(parts[i]).toString(16); if (parts[i].length == 1) parts[i] = ‘0’ + parts[i]; } … Read more
The best explanation is that the RGB color model is somewhat unintuitive for us humans. It’s perfectly logical for a video display device (such as a monitor or television) that only knows how to display colors by mixing varying amounts of 3 pre-defined colors: red, green, and blue. But that’s not how you and I … Read more
This may be slightly late, but to clear up the confusion with the use of &0xff: In Java ints are 32 bits, so the (A)RGB values for each pixel are packed in 4 bytes. In other words, a pixel with the values R(123), G(93), B(49) = FF7B 5D31 in the ARGB_8888 model. Where Alpha = … Read more
HSL Colors Using HSL Colors colors may be the easiest. HSL color values are specified in CSS as hsl( hue, saturation%, lightness%) where hue is in range 0-360 (without a unit marker when using degrees), and both saturation and lightness are percentages 0-100 with a trailing % sign. Note “Bright” colors refer to the colors … Read more
You can use VBA – something like Range(“A1:A6”).Interior.Color = RGB(127,187,199) Just pass in the cell value.
One option which greatly improves the quality of the resulting image is to convert to a different color space in order to more easily select your colors. In particular, the HSV color space defines pixel colors in terms of their hue (the color), saturation (the amount of color), and value (the brightness of the color). … Read more
