## Block Coloring Logic > low value of this color range

 [2023-10-15 15:38:08] #1 User303857 - Posts: 40 Hello Support, looking for some clarification on this page: Market Depth Historical Graph: Block Coloring Logic Example 1 - Interpolation to Background Color with Percent Color Thresholds: The following example uses only the Ask depths for simplicity. The data and Inputs are as follows: Maximum Depth Value: 1000 Minimum Depth Value: 0 Range 3 Max Ask Color: Grey (RGB values of 100, 100, 100) Background Color: Black (RGB values of 0, 0, 0) Highest Quantity for Coloring: 0 Lowest Quantity for Coloring: 0 Percent Color Thresholds: .25, .5, .75 Minimum Volume Intensity Percent: 0 Depth Value: 850 On all 3 of the examples it has: Since the Minimum Volume Intensity Percent is zero, the full range of possible colors for this Color Range will be used. The low value of this color range is 750 (.75 * 1000) and the high value within this color range is 1000, therefore this Depth Value equates to a Color Percentage of 0.4 ((850 - 750) / (1000 - 750)). ------------------- Why is .75 the low value when .25 is smaller? What is the logic here? Are the percent color thresholds the color range? Thanks
 [2023-10-16 15:01:28] #2 John - SC Support - Posts: 29568 This is an example of what color would get used for a depth value of 850. Since there is no Minimum Volume Intensity Percentage applied, the range of values that fall into the Range 3 coloring goes from 750 to 1000. The rest finds where within this range the value of 850 would fall.

 [2023-10-16 20:12:49] #3 User303857 - Posts: 40 So both of the other color thresholds will not be visible, since 0.85 is above both .25 & .50 , correct? Until it moves lower than the .75 range? Thanks

Other blocks may use other colors if the particular market depth value at that price and time falls into the particular color range.
