Color Alternation

Color Alternation problems feature figures that change color in a pattern while the shape often remains constant. The colors may alternate between two colors, cycle through three or more colors, or follow a specific sequence (e.g., Red→Blue→Green→Red). You must identify the color pattern and predict the next figure's color.

Introduction to Color Alternation

Color Alternation problems feature figures that change color in a pattern while the shape often remains constant. The colors may alternate between two colors, cycle through three or more colors, or follow a specific sequence (e.g., Red→Blue→Green→Red). You must identify the color pattern and predict the next figure's color.

Prerequisites

Basic color recognition Alternating pattern concept Cyclic sequences Pattern prediction
Why This Matters: Color Alternation problems appear in 1-2 questions in SSC CGL and Banking PO exams. They test pattern recognition in color sequences.

How to Solve Color Alternation Problems

1

Step 1: Identify the colors of the figures in the series

2

Step 2: Look for alternating pattern (A,B,A,B,...)

3

Step 3: Look for cyclic pattern (A,B,C,A,B,C,...)

4

Step 4: Determine the period of the color sequence

5

Step 5: Apply the pattern to the last figure's position to find next color

6

Step 6: Shape, size, and orientation usually remain constant

7

Step 7: Select the figure with the predicted color

Pro Strategy: Write out the color sequence. For two-color alternation, the pattern repeats every 2 steps. For three or more colors, find the cycle length (e.g., 3 for A,B,C). Apply the cycle to predict the next color based on position index.

Example Problem

Example: Colors: Red, Blue, Red, Blue, ___. Find the next color. Solution: Step 1: Colors: R, B, R, B Step 2: Pattern alternates between R and B Step 3: Last color = Blue Step 4: Next color = Red Answer: Red figure

Pro Tips & Tricks

  • Two-color alternation: A,B,A,B,A,B,...
  • Three-color cycle: A,B,C,A,B,C,...
  • Four-color cycle: A,B,C,D,A,B,C,D,...
  • Colors may include: Red, Blue, Green, Yellow, Orange, Purple, Black, White
  • Fill may be solid, patterned, or gradient (exams usually use solid colors)
  • Color changes may be combined with other transformations

Shortcut Methods to Solve Faster

If pattern alternates: next = opposite of last
If pattern cycles: next = color at (last_index + 1) mod cycle_length
Position parity (odd/even) determines color for alternating patterns
Use color names or hex codes to track sequence

Common Mistakes to Avoid

Not noticing that multiple colors are in a cycle (assuming simple alternation)
Confusing the color sequence order
Forgetting that shape may also change while color alternates
Assuming color is the only changing attribute
