I'm using react-native-mathjax to render some equations inside a green color view, but math equations displays with white color background, is there any way to change its back ground color ?
I have an image loaded into a picture box, and need some help with a way to detect the Darkest color present in the image, the Lightest color present, and the color which is in the middle.
The point being so that I can refine my heightmap generator based on these 3 colors.
I'm thinking of looping through each X,Y coordinate within the picture box, set the darkest and lightest value, and overwrite those values if a darker/lighter one is found.
The part I'm stuck at is determining what exactly I can use to check how dark or light a spot within the picture box is. RGB?
Any guidance is appreciated.

Hi guys! I have the following task: I must paint the black and white house, leaning to a result as the colored one.
I figured out, there must be a way to somehow "remove" the white color, so there is only the black outlines left. From there I will make an underlayer and will insert color/materials etc.
The hard part and the essential in my question is: The black outlines are ranging from true black to very light grey. Is there a way I can somehow delete all white (0,0,0) pixels and for the others: the more "black" they have, the more opacity they get. So a grey pixel with a value around (126,126,126) will be left, but with a 50% opacity.
have you tried, copying the same image on top of the original image, change the copied image blending mode to overlay, use the select tool on the white area, and then click the select tab on top menu, from that tab click select similar,so you have all the white area selected, then select the original layer, and then erase, you can also erase delete the copied image. Good Luck!
Yes you can,
Open "Select" menu and choose "Color Range", it will open a dialog box, inside that box you can choose from the drop down at the top if you want to select Reds, Yellows, Greens, etc. or you can select Sampled Colors with the eyedropper tool, so you can select the white color from anywhere at the image then you can handle the color range sensitivity from the slide bar called Fuzziness, the lower number is the lower range of white color and vise versa :)
As Ahmed Alaa said, use the "Color Range" tool, but for coloring in black and white images, see if my Youtube tutorial can help.

P.S. Sorry this post is bad, i'm new-ish.
I have this element in my psd layout
I need to remove green rectangle and leave a gray box with a gap at the top (in place of the green rectangle) and save as .png. How can I remove green rectangle?
select Magic Wand Tool (press W on keyboard), then select the
green area and then press Backspace to remove it.
Then Create new Layer with white background and set it as background
layer,
Then create your own gray layer.
I'm trying to understand how the normal blend mode works in photoshop.
http://www.pegtop.net/delphi/articles/blendmodes/normal.htm
As the webpage says,it just shows the color of the layer above.But when I copy the same layer and show them together,the color seems darker than just show one layer.And when I add more,the color remains at a particular value.
The normal blend mode shows the color of the topmost fully opaque layer, for transparent layers it will add from top down until fully opaque is reached.
This means that if you have a fully opaque red element over any, for example, blue element, the color red will be displayed. If you have a red element that's 50% transparent over a blue element, the color pink will be displayed.
If you have one black element that is 50% transparent it will appear as a medium gray, if you duplicate the layer, the two elements on top of each other will add up to display a complete black.
