Jpeg supports up to 24 bit RBG (2^24 colors).
Photoshop supports images up to 32 bit/channel.
A standard 24bit JPG file can have up to 16,777,216 different colours. This is split by 8 bits for each Red, Green and Blue component. 2 to the power of 8 is 256. So each of the red, green and blue components has 256 different shades, combining these together gets us 256*256*256 = 16,777,216. More or less bits can be allocated to the RGB components of a jpg file but it should follow roughly the same principle.
GIF format supports up to 8 bits per pixel, allowing a single image to reference a palette of up to 256 distinct colors chosen from the 24-bit RGB color space.JPEG files embed an ICC color profile (color space). Commonly used color profiles include sRGB and Adobe RGB which are often 24 bit (16.7 million colors). 255 255*255*255
jpeg takes up less
JPEG is a bitmap file type. There are many bitmap file types but JPEG is the one which uses the least amount of memory. However, JPEG image file sizes can be changed by how they are saved in the data loss compression feature which JPEG uses.
It's probably because of the image format you saved it in. I save my pixel art in nameoffile.PNG format. .GIF - Saves images with up to 256 different colours. Small filesize allows fast loading. Loss of image quality only occurs when you excede 256 colours, though it is unlikely you will reach this point unless you are saving a composite of many sprites. .PNG - Similiar to gif, except that it will allow you to save images with more than 256 colours without image loss. Technically better, but not well supported by Internet Explorer (boo, hiss). There ya go! =)
The Compaq Armada supports up to 256 MB of SDRAM. If you have less than this amount (most models came with 64 MB to 128 MB), you can upgrade it.
Hang Up Your Brightest Colours was created in 1973.
Just keep levelling up until you reach 256
Yes, generally speaking JPEG compresses best of all graphic formats (with loss of image information).
1 x 256, 2 x 128, 4 x 64, 8 x 32, 16 x 16 = 256
primary colours make up secondary colours its as simple as that
