I have this pixel graphic in which I want to turn blue parts into red. So I use the "select color" tool to select the blue part of the image, drag the brightest red possible onto the selected area and it turns out brown. Any idea what I'm doing wrong? Thank you and happy holidays!


Your image is likely color-indexed (loaded a GIF?) and the colors you want are mapped to the closest color available in the color map.

Convert it to full RGB (Image>Mode>RGB).
