how to make an image a colored bit map

[jackz55333210]

so i know how to make a image into bitmap mode, but thats a back and white image, i know i can convert it into grayscale and then rgb then colorize it, but thats only one tone. is there a way i can make an image into a colored one like this ?

thanks

You can duplicate image then convert to bitmap for example. Copy bitmap image and paste into RGB colored image then use blending mode for example to mix both worlds if that is what you are looking for. Have you tried that?

A bit of a lengthy process, but take a color image and duplicate it, and name it red. Convert it to a grayscale image. Use apply image on the red file to apply the red channel to the main layer in the red file (you can also copy and paste it). Duplicate the red file twice and call one file green and the other blue. Do the same thing with applying the green and blue channels respectively of the original file to those duplicate files. Change the red, green and blue files to bitmap files. Create another duplicate file of your original file. Now you have to copy and paste the red bitmap layer to the red channel of the new duplicated original file. Do the same with the green and blue files.

how come it looks so noisy, like you see in the image there are parts that are just solid colors and there are like cross hatches going on, instead of one same texture

i think your method works best, this is what i got out of it. 

however, i think there is still a detail missing, you see how in the reference image i uploaded in the question there are parts of the colors that are just solid and free of texture? like this blue in the sky :

i'm still now clear on how i would be able to do that. would you know what i'm doing wrong ?

thanks

this is the furthest i've gotten by lowering output bitmap quality to 50 pixels per inch

Most like the settings and resolution that I used.

I've been playing around with this, and I think I have it. first convert your image to index color, using around 15 colors, and use pattern as the dither option. Then use save as and select bmp as the file type. Chose 4 bit. save and reopen file.
