基于颜色应该做到以单字节为基本。目前是4字节。

基于颜色： <input type="text" name="basecolor" value="ffff" size="40" />

颜色跳距离:<input type="text" name="step" value="1" size="40" />
显示列:<select name="loop">
<option value="1">1</option><option value="2">2</option><option value="3">3</option><option value="4">4</option>
</select>
 <input type="hidden" name="checked" value="1" />
<input type="submit" value="submit" />
