Color picker helps you pick a color in HEX, RGB, RGBA, CMYK and HSV color model record. Click on the field of color selection, and for a more precise selection, move the cursor while holding the left mouse button. Change the color settings via input fields.
Also, you can download the color selected. Click on the button "Download color", that will appear at the settings box. You can choose the format (SVG, PNG, JPEG or GIF), and image size. Please note that the semi-permanent color can only be downloaded in SVG and PNG format.
Your comment would be nice :)
